General Information

  • What is a thermometer?

    A thermometer is an instrument that is used to measure temperature. Traditionally, thermometers consisted of a glass tube with a bulb at the end containing mercury, which would extend along the tube as it expanded to react to fluctuations in temperature. Nowadays, most industrial thermometers are digital.

Food Temperature Guidelines

  • Why are recommended Sous Vide cooking temperatures so much lower than other recommended cooking temperatures?

    Sous Vide cooking temperature are so much lower than other cooking temperatures simply because they are kept at cooking temperature for a lot longer.

  • How accurate should my food thermometer be?

    HACCP guidelines recommend that food thermometers are accurate to within +/- 0.5°C. All TME-made thermometers and probes are at least this accurate, and most of our equipment is accurate to within +/- 0.25°C

  • What are critical food safety temperatures?

    The most common food safety temperatures, as advised by HACCP, are as follows:

     Frozen food to be kept at -18°C of below

    Refrigerated food to be kept at 8°C or below

    Cooked food to reach temperature of 75°C
    Hot food to be held at 63°C

    When reheating, food should reach temperature of 82°C

     -          These critical temperatures are subject to variation depending on your agreement with your enforcement officer. For example, it is safe to cook food at less than 75°C, provided that the cooking time of the food is increased accordingly.

  • What are HACCP guidelines?

    “HACCP (Hazard Analysis and Critical Control Point) is a system that helps food business operators look at how they handle food and introduces procedures to make sure the food produced is safe to eat.” - http://www.food.gov.uk/business-industry/caterers/haccp

    HACCP guidelines are put in place by the Food Standards Agency (FSA). Some of the HACCP guidelines that relate to temperature are:

    A food temperature of 8°C or below is effective in controlling the multiplication of most bacteria in perishable food. It is recommended practice to operate refrigerators and chills at 5°C or below.

    Freezing: Freezing of food at temperature of -18°C or below will prevent bacteria multiplying.

    Cooking: Temperatures of 75°C or above are effective in destroying almost all types of bacteria. However, cooking temperatures below this level are also effective provided that the food is held at these temperatures for a suitable time period. (refer to the Cooking HACCP chart)

    Hot holding: Temperature above 63°C will control the multiplication in hot food.

    Cooling: Food should be cooled as quickly as possible and then refrigerated. This will limit the growth of any bacteria or germination of spores that may be present.

    Reheating: All food that has previously been heated and is to be re-heated, must be raised to a temperature of 82°C, which will ensure that the food has been reheated to a safe and, in some cases, legally required temperature. Using a suitable time/temperature combination will also ensure that food has been reheated safely should higher temperatures be detrimental to the quality of the food, for example reaching a core temperature of 70°C for 2 minutes.” - https://www.food.gov.uk/sites/default/files/multimedia/pdfs/cshrtempcontrol.pdf


  • Do all TME digital handheld thermometers come with a battery?

    Yes. All out digital handheld thermometers come supplied with a 9v PP3 battery.

  • How long will the battery last?

    The battery should last for more than 200 hours of intermittent use, although it will depend on how much it is used.

  • What does 'self-calibrating' mean

    All our instruments have a voltage reference, and they use this to check their own calibration “ Self-Calibrating”. However although this gives us excellent long term stability for many customers they also require an annual calibration check or certificate to external sources.

  • What does T type thermocouple mean?

    TME mainly offer two types of thermocouple – K and T. The CA2005 only accepts T type thermocouple. T type thermocouples are high accuracy and ideal for food and catering applications.

  • How waterproof is the CA2005?

    The CA2005 has an IP67 rating which means that it is completely waterproof. This protection means that the unit shouldn’t come to harm if accidently submersed.

  • How does the dual display work?

    The CA2005 offers a hold function and when this button is pressed, the current temperature will be held and transferred to the top right of the display. The main display will continue to show the temperature in real-time.

  • How do I replace the battery in a TME digital handheld thermometer?

    All TME digital handheld thermometers have a battery compartment located on the rear of the instrument. Simply open the battery compartment, remove the battery and replace.

  • Do I need to buy a probe with my thermometer?

    If you don’t have any kind of probe, you won’t be able to use your thermometer. A thermometer, as we have established, translates a signal from a probe or sensor, therefore in order to have something to translate, you will need to plug a sensor into it. Be careful though, as some thermometers are supplied complete with probes, or have probes built-in. For example, TME’s SOLO thermometer has a built-in needle probe, which is attached to, and swings out of the body of the thermometer. If you need a thermometer which you only use for one application (such as measuring core food temperature), these kinds of thermometers are a useful option. If, however, you know that you want your thermometer to measure different types of things (air and water, for example), you may want to think about a temperature kit. These offer a thermometer with (usually) more than one different type of probe, and TME offer a wide variety, tailored for different applications.

  • What is the difference between a thermometer and a probe?

    Simply put, the thermometer is the ‘box’, where you will see a screen that displays measurements, and the probe is the thing connected to it. So the probe (or sensor), senses the temperature and sends a signal to the thermometer, which translates it into a figure (usually °C or °F) and displays it. Probes can come in many different varieties which are designed to suit a specific application (such as needle probes, flat food probes, air probes etc). Thermometers, too, can have many different applications in addition to displaying a temperature reading. Some thermometers have a hold function, or can calibrate other thermometers, scan barcodes or wirelessly send temperature readings to other electronic equipment such as PCs or PDAs.

  • What is an IP rating?

    IP (Ingress Protection) ratings are defined by an international standard. They define levels of effectiveness for sealing electrical enclosures against intrusion from moisture and dust. Each number of an IP rating has a specific meaning. For example, TME’s MM2000 digital thermometer has an IP rating of 67. IP67 enclosures translate as IP rated for ‘dust tight’ (that’s the 6), and protected against immersion in up to 1m of water for up to 30mins (that’s the 7). So the MM2000 is referred to as being IP67 waterproof.

  • Can I send my thermometer away to be calibrated?

    You can. TME offer a repair/calibration service, which is covered by the Thermometer for Life guarantee that comes with your thermometer, and should cost £35 for a MM2000 series thermometer, or £55 for a MM7000 series thermometer. You can see proof of this calibration as the sticker on the inside battery compartment of your thermometer will be updated and replaced. Please remember that this service will ensure calibration of your thermometer, but will not include a certificate of calibration, as generating the certificate is a different process (explained below).

    To have your thermometer calibrated/repaired, simply send the thermometer back to our Production Department with a note explaining what it is that you require.

  • Can I get a calibration certificate on this item?

    Yes. This would be for our standard UKAS traceable certificate for a cost of £35.00. Please email sales@tmethermometers.com with the four temperature points required.

  • Can I calibrate a probe?

    Generally speaking, it isn’t worth calibrating a probe, as the cost of calibration can be greater than buying a new probe. Indeed, it isn’t possible to calibrate a probe on its’ own. But if you want a thermometer calibrated with a specific probe, it is known as a System Calibration, and will cost £55. Again, you will need to send your thermometer back to us, with the probe, to be calibrated.

  • I need a certificate of conformance for my thermometer, what should I do?

    We are happy to provide a certificate of conformance for any of our equipment. This certificate lists the product and (if it’s a thermometer), the product’s serial number, and affirms that the product has been made in accordance with the appropriate specifications and guidelines required. We do not charge for a certificate of conformance, and you will not need to send your thermometer back to us to receive one. We can email the certificate (signed by our Production Manager) directly to you.

  • I need a certificate of calibration for my thermometer, what should I do?

    TME are happy to issue a certificate of calibration for your thermometer. You will need to send your thermometer back to our Production Department with a note explaining that you require a certificate of calibration, and also listing the temperature points that you would like it to be calibrated at. These usually comprise of some of the critical temperatures that you need for your thermometers’ application. For example, if you are testing for legionella, your critical temperatures will be 20°C for cold water and 50 or 55°C for hot water. You might also want to calibrate at 0°C and at the upper limit of your measurement range, such as 100°C. Generating a calibration certificate can be a lengthy process, as the thermometer needs to be calibrated and several points, and so we charge £35 for a certificate of calibration. Your EHO might want you to have your thermometer re-calibrated yearly.

  • How do I calibrate my thermometer?

    To test the calibration of your thermometer yourself, prepare a solution of ice and water, and insert your probe into it. Your thermometer should read 0°C. If it is out of calibration, firstly try using a different probe, just in case it is your probe that is faulty, and if that doesn’t make a difference, contact us for advice – you may need to send your thermometer back for a repair/calibration.

  • How often should I calibrate my thermometer?

    Different Environmental Health Officers and HACCP Officers will require different levels of calibration. You should always follow the advice of your EHO on calibration. At TME, we are happy for the calibration of thermometers to be tested weekly, which you can do yourself. Most EHOs advise a yearly re-calibration of your thermometer and/or probe, which would consist of sending your thermometer away to be calibrated.

Data Logging

  • What is a data logger?

    A data logger is an electronic device that records data over time or distance. TME supplies several different temperature data loggers for different uses. Most temperature data loggers are small, battery powered and use a microprocessor, internal memory, and an external or internal temperature sensor. Some dataloggers can send data in realtime, using WiFi, and some can download easily to a computer using an induction pad or wired connection. All of the data loggers that TME supplies can be sold with their own software. Some of the TME data loggers have digital displays, and some can come with built in alarms for out-of-range temperatures.

    The benefit of using a data logger for temperature is that it collects data on its’ own, with no need to carry out spot checks etc. This means that you can keep a constant log in changes to temperature, which can be very useful for some applications, including transport. However, data logging thermometers tend to be quite expensive, especially with the added cost of software, and do not allow you to record information about specific items/products, as you would need to for spot checks, so it’s worth thinking hard before you decide whether or not to buy a data logger or a normal thermometer.

MM7000 Range

  • How do I turn my MM7000 range thermometer on and off?

    Different thermometers within the MM7000 range have different configurations of buttons, but the on/off button is the same for all of them. Simply press the top left hand button:  once to turn the thermometer on, and again to turn it off.

  • Can I print the temperature readings from my MM7000 range thermometer?

    You can. For a complete guide on how to print temperature readings from your thermometer, please see page 11 of the MM7000 range handbook: https://www.tmethermometers.com/downloads/dl/file/id/23/mm7000_handbook.pdf

  • How do I download readings from my MM7000 range thermometer?

    For a complete guide on how to download readings from your MM7000 range thermometer, please see page 9 of the MM7000 range handbook: https://www.tmethermometers.com/downloads/dl/file/id/23/mm7000_handbook.pdf

  • How do I assign barcodes to my temperature testing points?

    For a complete guide on how to assign barcodes to your temperature testing points, please see page 8 of the MM7000 range handbook: https://www.tmethermometers.com/downloads/dl/file/id/23/mm7000_handbook.pdf

  • How do I replace the battery in my MM7000 range thermometer?

    Replacing the battery in your MM7000 range thermometer is very easy. Simply open the battery compartment in the back of the thermometer, remove the battery and replace with a new one.

  • How long will the battery in my MM7000 range thermometer last?

    It depends on how much you use it, but the battery should last for more than 200 hours of intermittent use.

  • Does my MM7000 range thermometer come with a battery?

    Yes it does. Your MM7000 range thermometer comes with one standard 9 volt PP3 battery

  • How do I set up the software for my MM7000 range thermometer?

    Firstly, you’ll need to download the software from the relevant product page on the TME website. There will be a button with an arrow on it – this is your download button. You will also be given a software CD with your MM7000 range thermometer purchase, and you can download the software onto your PC from there instead if you wish. Full instructions on the setup of software for the MM7000 range thermometers are here: https://www.tmethermometers.com/downloads/dl/file/id/23/mm7000_handbook.pdf

  • Why does the MM7000 range of thermometers use Barcode technology?

     When designing the MM7000, we looked at the problems that users often have when carrying out temperature spot checks. One of the biggest of these was the issue of not being able to record the identity of the product/item/location being monitored. Any thermometer with a hold function can give a record of the time, date and temperature of a measurement, but there was no way of recording the identity of the measurement. Barcode technology is the obvious answer. Barcodes are free and easy to generate (there is even now a Barcode font in newer versions of Microsoft Office), and they can be manipulated to mean anything you want them to. Barcodes also are often already assigned to products, for example in a goods in scenario. The MM7000 range includes one extra step in taking temperature measurements: simply scan the barcode that relates to the product/item/location you are testing, and you have a complete temperature record – no filling out a written log book, no room for human error.

  • How can I switch between F° and C°?

    All you need to do to switch between F° and C° on most MM7000 range thermometers is press the SCALE button (SCL).

Thermometer Types

  • What is a thermistor thermometer?

    A thermistor thermometer measures electrical resistance proportional to temperature. The name ‘thermistor’ comes from a combination of the words ‘resistor’ and ‘thermal’. PTC thermistors, which are the kind of thermistor that TME supplies, stands for Positive Temperature Coefficient of Resistance. PTC thermistors have resistances that vary in line with their temperature, so when the temperature increases, so does the resistance. PTCs are constructed using semiconductors that are combined with ceramics or polymers. Thermistors are most commonly found for medical temperature applications, as well as within cars, computers, home appliances and more, as they provide protection against circuits overheating. Thermistors are very stable, long lasting, and more accurate than thermocouple thermometers. However they cannot be used at extreme temperatures, and generally can only measure between 0 and 100°C, which makes them less desirable for food manufacture or catering use.

    In Summary

    Temperature range          : Poor

    Accuracy                          : Good

    Time Response                : Poor

  • What is a PT100 Thermometer?

    PT100 thermometers, also known as resistance thermometers or PRT (platinum resistance thermometers), measure temperature by correlating the electrical resistance of a resistance temperature detector (RTD) element with temperature. The element inside of a PT100 thermometer is platinum (PT), and the 100 stands for a resistance of 100Ω (ohms) at 0°C.

    Resistance thermometers are generally used when greater stability, accuracy and repeatability is required than is available from a thermocouple thermometer. However, PT100 thermometers cannot be used at very high temperatures (above around 500°C), so they are less useful for manufacturing processes. They also do not have as quick a response time as thermocouples.

    In Summary:

    Temperature range          : Good

    Accuracy                          : Good

    Time Response                : Poor

  • What is a thermocouple thermometer?

    Thermocouple thermometers are the most widely used thermometer in the modern day. Thermocouples use electrical technology to show temperature. A thermocouple ‘couples’ together two different metals, one that is contained within the thermocouple thermometer, and one that forms a probe or sensor, to test the temperature of a substance or atmosphere. The difference in the temperatures of the two metals is expressed electrically through their different voltages. The temperature of the metal inside the thermocouple is already known, so the difference between the two temperatures allows us to easily deduce the temperature of the metal attached to the probe. The deduction is carried out using a microchip inside of the thermometer, and the temperature that the probe has sensed then shows on the display.

    Thermocouples are essential in many heating, manufacturing and electrical engineering applications, and can be found in different thermocouple types, according to the different metals used in the probes. Thermocouples have the advantage of a very fast response and large potential measurement range – from -270 to 1,800°C.

    TME thermocouple thermometers are compatible with several different thermocouple types (such as K/T/J/R/N/E/S). Most TME probes are in T type (for food applications) or K type (for non-food application), although we do manufacture probes in all different thermocouple types.

    In Summary ( Type T Thermocouple)

    Temperature range          : Good

    Accuracy                         : Good

    Time Response               : Good

  • What is an infrared thermometer?

    Infrared thermometers are thermometers that measure infrared light radiating from the surface of an object. Infrared signals can be correlated to specific temperatures, which is how they can obtain a temperature reading without direct contact to the object being read. Infrared thermometers can be useful when it is not possible to obtain direct contact with the object being measured, due to it being in a controlled atmosphere, moving very fast, or when contact would contaminate the object.

    It is important to remember that infrared thermometers are not able to provide the accuracy that is often required, especially for food or water temperature testing. This is because an infrared thermometer measures the surface temperature only, and because there is no contact with the object measured, it will often not even measure the surface temperature of an object, but instead, measure the temperature of the air in front of the object.  

    The fundamental accuracy typically achievable in laboratory conditions is ±2°C, in real life situations however this is rarely achieved. As a rule of thumb the colder the temperature the less accurate an infra red measurement is.

MM2000 Range

  • How do I turn my MM2000 range thermometer on and off?

    Different thermometers within the MM2000 range have different configurations of buttons, but the on/off button is the same for all of them. Simply press the top left hand button:   once to turn the thermometer on, and again to turn it off.

  • How do I activate my MM2000 range thermometers’ Thermometer for Life policy?

    If you purchase an MM2000 range thermometer, whether directly from TME or from one of our suppliers, you automatically qualify for the Thermometer for Life policy. If your thermometer breaks, simply send it back to TME’s production department, who will repair/replace it for no more than £35. This is a lifelong guarantee and does not affect your standard 2 year warranty.

  • How can I switch between °F and °C?

    All you need to do to switch between °F and °C on MM2000 range thermometers is press the SCALE button (SCL).

  • Does my MM2000 range thermometer come with a battery?

    Yes it does. Your MM2000 range thermometer comes with one standard 9 volt PP3 battery.

  • How do I replace the battery in my MM2000 range thermometer?

    Replacing the battery in your MM2000 range thermometer is very easy. Simply remove the protective rubber boot, open the battery compartment in the back of the thermometer, remove the battery and replace with a new one.

  • How long will the battery in my MM2000 range thermometer last?

    It depends on how much you use it, but the battery should last for more than 200 hours of intermittent use.

  • Is my MM2000 range thermometer still waterproof without its rubber boot?

    Yes. The rubber boots that come with MM2000 range thermometers are intended to increase the shock-proofing of the instruments. They have no effect on the waterproofing.

  • Is the MM2000 range of thermometers waterproof?

    Yes. The MM2000 range of thermometers is waterproof to IP67 standard, meaning that it is submersible.

Food Applications

  • Is the CA2005 available with a wall mount holder?

    We can supply a choice of two hygienic stainless steel wall storage units easily installed by fixing to a wall using screws and the keyhole slots provided.

    The CAWALLMOUNT holder can accommodate 1 x thermometer and up to 6 colour coded probes and is manufactured with colour coded slots to help keep probes separate and to provide visual guidance on different food group colours. The MMWALLHOLD can accommodate 1 x thermometer and up to 2 standard TME probes.

  • What is the colour coding for?

    TME have developed colour coded needle probes to help reduce the risk of bacterial cross-contamination between different food groups. Each probe handle is colour coded so it can be assigned to a particular food group: RED = Raw Meat, BLUE = Cooked Fish, YELLOW = Cooked Meat, GREEN = Washed Salad/Fruit, WHITE = Bakery and Dairy, BROWN = Vegetables.

  • Are the CAP probes waterproof?

    The CAP probes have a fully waterproof construction and can even be cleaned and sterilized within a dishwasher or ware-washer.

  • Is the CA2005 range HACCP compliant?

    Yes, our CA2005 and CAP probes offer an overall accuracy which is better than ±0.5⁰C

  • Does the colour coded CA2005 range conform to government regulations?

    Whilst there are no government regulations applied to colour coding in the food and hospitality industry, TME use standard colour coding which is widely accepted.

  • Are the CAP probes specifically for catering use?

    The CAP range of needle probes have been designed with the catering industry in mind but they can be used in most applications which requires the core temperature measurement of products.

  • What T type thermocouple probes can I use with the CA2005?

    TME have developed a range of colour coded catering probes which are perfect for use with the CA2005. Our full range of T type thermocouple probes can be used with the CA2005.

  • How can I measure the temperature of food that is vacuum-packed for Sous Vide cooking?

    Sous Vide cooking is a growing phenomenon in catering and hospitality, but it can be difficult to measure the core temperature of vacuum-packed food. TME manufactures a temperature kit especially for Sous Vide cooking. The SVK1 includes a thermometer, a super-fine needle probe and self-sealing foam tape, which allows you to measure the temperature inside a vacuum-packed bag without breaking the seal of the bag, which can be disastrous for this kind of cooking. The needle probe in this kit is just 1.5mm in diameter.

  • How can I measure the temperature of solidly frozen food?

    The biggest problem that you will encounter when trying to measure the temperature of solidly frozen food is how to reach the core of the product whilst the food is still frozen. TME manufacturers more than one probe to help with this issue. Most popular is the TP01 Frozen Food/Corkscrew Probe, which is designed to be ‘screwed in’ to solidly frozen food, using its corkscrew design to allow for easy penetration of the product. We do not recommend using a surface or infra-red probe on solidly frozen food, as it will not give the core temperature of the product.

  • How can I measure the temperature of my cold store/fridge/freezer?

    The best way to measure the temperature of a cold store/fridge/freezer is to use an accurate, good quality probe with a long response time that you can leave in your appliance. A long response time means that your probe will fluctuate in temperature at a similar speed to a pack of meat, so that there isn’t a big change in temperature every time the door is opened. TME’s Food Simulator Probe, which is designed to have similar thermal characteristics as a pack of meat, can be attached to the inside of a cold store/fridge/freezer, with the thermometer only needing to be ‘plugged in’ when temperature checks are carried out. There are several low-cost dial thermometers that can be used to measure the temperature of cold stores/fridges/freezers, but these are not recommended for commercial appliances, as they are not sufficiently accurate or reliable to comply with HACCP regulations.

Solo Thermometer

  • How do I replace the batteries in my SOLO thermometer?

    Replacing the battery in your SOLO thermometer is very easy. Simply open the battery compartment in the back of the thermometer, remove the battery and replace with new ones.

  • How long will the battery in my SOLO thermometer last?

     It always depends on frequency of use, but when used intermittently, your batteries should last for more than 500 hours.

  • Does my SOLO thermometer come with a battery, and what kind of battery does it use?

    Yes. The SOLO Thermometer is supplied complete with two AA batteries.

  • Is a SOLO thermometer HACCP compatible?

    It is. HACCP guidelines recommend that food thermometers are accurate to within +/- 0.5°C, which is the same accuracy as the SOLO thermometer.

  • What is a SOLO thermometer?

    A SOLO thermometer is an easy-to-use, buttonless thermocouple thermometer, which comes complete with a foldout needle probe attached. It is perfect for use across all kinds of food temperature measurement.

  • How do I turn my SOLO thermometer on and off?

    To turn your SOLO thermometer on, simply swing the needle probe out. To turn it back off again, fold the needle probe back into its resting position. If you leave the needle folded out, don’t worry, it won’t drain all of your battery. The thermometer will turn itself off after it’s been left unfolded for 10 mins.

  • Why is my SOLO thermometer so fast?

    When you start to use the SOLO thermometer, you may be surprised at how much quicker it is than other thermometers you might have used in the past. This is because the needle probe which is attached to the thermometer is built using ThermoSprint technology, which delivers an incredible response time of just 3 seconds – that’s up to 10 times faster than the competition.

Legionella Testing

  • Can I immerse this probe in water?

    Yes, the KS20-S is completely waterproof.

  • What does ' Dual Surface/Immersion' mean?

    This probe is essentially for taking surface temperatures of solid objects, such as water pipes. However, the tip of the probe is fully waterproof which means it can also be immersed in water to take running and standing water temperatures.

  • Do I have to stand in the shower to use the probe?

    The length of the probe stem means that in most cases you should be able to stand outside the shower cubicle. The angle of the cup together with the design of the probe handle means that water shouldn’t run down your arm when using the probe.

  • Why is the KM08 Shower temperature Probe better for shower temperature measurement than a standard immersion probe?

    The KM08 Shower Probe has been carefully designed to give a fast, accurate temperature reading in showers whilst keeping your arm dry. The small cup at the end collects and circulates water around the built-in temperature sensor. This gives a much more reliable temperature measurement than holding a standard probe in the shower spray. The angle of the cup, length of the probe stem and the handle design help to keep the operator dry.

  • How do I use the KM08 Shower Temperature Probe?

    Plug the probe into a K-type digital thermometer (we recommend our MM2008 waterproof  model with built-in timer for H&C running times). Turn on the shower and hold the probe cup just below the showerhead ensuring the cup continuously overflows. Keep the cup in the water stream until the temperature settles or the desired temperature is reached.

  • What probes will I need for water temperature testing?

    You will need an immersion probe for running water (KM03 or TM03),  and a surface probe for pipe surface temperatures (KS07 or TS07).

    Alternatively, choose one of our excellent dual probes which do both  Immersion and surface temperatures (KS01-S, BSKS01-S or KS16-S).

    You can also use fine wire probes (KA01 or TA01) to attach to pipes or valves that are difficult to access. See TCWALLPORT for more details.

  • Can I use the probe for running water temperatures?

    Yes the BSKS01S/KS01-S is designed for both immersion and pipe surface temperatures.

  • Can I use other probes with the thermometer?

    Yes, you can use any TME thermocouple probes with this thermometer. Probes are available to buy individually or in kits

  • Is a holster or case available for this kit?

    Yes, the MMHOLS holster or GPC02 Carry Case are both suitable.

  • Why is the MM2008 the best option for water temperature testing?

    HSE require hot water outlets to reach compliant temperature within 1 minute of running the water and two minutes for cold water outlets. The MM2008 has a built-in one and two minute timer which means you can easily mo.nitor the time and simultaneously read the temperature on the display

Fixed Monitoring

  • What is the TC Wall Port?

    The TC Wall Port is a wall-mounted temperature monitoring point, connected to a fine wire thermocouple temperature sensor. The tip of the sensor is permanently installed on the surface of the item you wish to take the temperature of, such as a water pipe or TMV inlet. Simply plug your thermometer into the port with a connector cable for an instant temperature reading. The port can be sited up to twenty metres from the test point making it ideal for use with boxed-in pipes and valves or pipes and water tanks located at height or in areas where access is difficult.

  • How many Temperature Transmitters can be used with one Notion Lite Base Unit?

    You can use up to 10 transmitters and can be a mix of either our NL-WT001F1 with internal sensor or the NL-WT003F1 with external sensor and with door-open alarms

  • What else is available for the Notion Lite?

    A range of external temperature probes is available for use with the Notion Lite as well as door alarm sensors. Please feel free to contact our sales team for more information.

  • What do I need in order to use the Notion Lite?

    A basic set-up requires a base station, temperature transmitter, power supply, Ethernet cable and subscription voucher. A starter kit is available (see product code: ‘NL-LK003F1’). The product code for the voucher is ‘NL-W613’. The starter kit includes 3 temperature transmitters. Additional temperature transmitters are also available – see our product code NL-WT001F1

  • How does the Notion Lite work?

    The Notion Lite uses cloud-based data storage so the user has the ability to access data 24/7 on any internet enabled device using a browser and unique username and password. The basic system consists of a temperature transmitter and base unit. The transmitter feeds data back to the base station, and the base station then feeds this data to a router with internet access.

  • What is the Notion Lite for?

    The Notion Lite is a temperature monitoring solution ideal for retail food outlets, pharmacies, medical clinics, smaller food processing plants and temperature controlled storage facilities. It is very simple to set-up and use and offers immediate access to real-time data, alarms and audit ready reports.

  • Can I use TC Wall Ports to measure flow and return pipe temperatures on calorifiers?

    Yes. Simply attach a fine wire sensor to each pipe and connect each one to a Wall Port sited in a convenient position. We recommend using high-temperature duct tape to fix the sensors to the pipes.

  • Can I use a TC Wall Port to measure temperature of water in a CWST?

    Yes. We recommend using a KM07 immersion probe to be hung in the tank and run to the Wall Port. This comes with a two metre cable as standard. Other lengths are available on request. Please see the diagram illustrating this on the TC Wall Port product page of our website.

  • Does the TC Wall Port system replace conventional temperature monitoring?

    The TC Wall Port system happily works alongside conventional temperature monitoring using handheld immersion and surface probes. Its main advantage lies in simplifying temperature monitoring of points which are boxed-in or are difficult to access. If you have any doubts regarding the implementation of a water temperature monitoring regime in your building, you should consult your risk assessment and adhere to any recommendations contained therein.

  • What is the purpose of the Red and Blue colour options for the TC Wall Port?

    Engineers often need to monitor both hot and cold pipes at the same location. The Red and Blue ports make it easy to tell which is hot and which is cold.

Breakages, Replacements and Repairs

  • I regularly need to replace my thermometers and probes, can I set up a service contract to cover the cost?

    If you have purchased a large number of TME thermometers/probes, and are likely to have a high turnover of breakages, we offer a swap service which charges a set monthly rate in return for an unlimited number of swaps. We can offer this on a next day basis. If you are interested in the swap system, please phone or email TME for advice on how best to set it up.

  • What is the Thermometer for Life guarantee?

    The Thermometer for Life guarantee promises that TME will repair/replace any TME thermometer that is accidentally damaged or malfunctions for no more than £35 (+VAT) for an MM2000 series thermometer, or £55 (+VAT) for an MM7000 series thermometer. As the name suggests, this guarantee is for life and exists outside of your normal warranty.

  • What is the warranty on my probe?

    TME probes do not come with a warranty, however if there is a fault in our manufacturing process we will of course replace for free.

  • What is the warranty on my thermometer?

    Most TME thermometers come with a standard 2 year warranty. The Thermometer for Life guarantee exists outside of the parameters of this warranty.

  • Will you replace my thermometer if it is broken?

    We will. Please see below for the details of our Thermometer for Life guarantee, which offers a repair/replacement of your thermometer at a fixed price, for life. 

  • My thermometer won’t turn on, what should I do?

    If your thermometer won’t turn on, the first thing to do is to replace the batteries with fresh ones. If this makes no difference, you may need to phone or email us to set up a repair.

  • My thermometer is showing an incorrect temperature, what should I do?

    If your thermometer is showing a temperature that you know to be incorrect, the first thing that you should do is ensure that it is set to the correct thermocouple type, as having a thermometer set to a different thermocouple type to your probe can result in an incorrect reading. Loosely speaking, if you probe has a green lead or plug, it is a K type thermocouple, and if it has a brown lead or plug, it is a T type thermocouple. Ensure that your thermometer is set to the same thermocouple type.

    If you are sure that your thermometer is set to the correct thermocouple type, but it is still showing an incorrect temperature, the next best thing to do is to try to use it with another probe (if you have one). If you plug a different probe into the thermometer and the reading is now correct, the likelihood is that there is a fault with your probe, not your thermometer.

    However, if you have tried both of these steps and your thermometer is still showing an incorrect reading, you can phone or email us to set up a repair.
