  • When is it important to use a thermometer?
    Question by: admin on 2018-09-05 11:54:29

    There are many different applications which require the use of a thermometer, from basic everyday tasks such as cooking or testing family members for a fever, to checking fridge/freezer/oven temperature, measuring water temperature to help prevent outbreaks of Legionnaires’ disease, reaching critical temperatures in a manufacturing process, maintaining temperatures during distribution of food products, tyre production, oil production, laboratory testing, facilities/building management and more. The risks of not having a thermometer for these applications vary from a burnt dinner to patients contracting a life-threatening disease.

  • What is the difference between a thermometer and a probe?
    Question by: admin on 2018-09-05 11:51:38

    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.

  • How often should I calibrate my thermometer?
    Question by: admin on 2018-09-05 11:45:58

    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.

  • What is the life expectancy of the KS20-S?
    Question by: admin on 2018-06-21 12:59:12

    Longevity will depend on a number of factors including frequency of use, environmental conditions and correct application (see 'How do I use the KS20-S to take surface temperature of a water pipe?').

  • What does 'High-Speed' mean?
    Question by: admin on 2018-06-21 12:39:27

    The probe is designed to have a very fast response to temperature changes. In tests with the MM2008 Legionella Thermometer, the probe was immersed in water at 50 degreesC and the temperature reading stabilised in less than ten seconds.

  • What probes will I need for water temperature testing?
    Question by: admin on 2018-06-20 13:19:29

    You will need an immersion probe for running water (KM03), and a surface probe for pipe surface temperatures (KS07). Alternatively, choose one of our excellent dual probes which do both Immersion and surface temperatures (KS20-S, KS01-S, BSKS01-S, or KS16-S). For areas that are difficult to access - ie valves or pipes, or high-traffic areas, such as school corridors, we recommend the TCWALLPORT System. This incorporates the use of fine wire probes (KA01) and a compact temperature monitoring point known as the TCWALLPORT

  • What are the required water temperatures for buildings?
    Question by: admin on 2018-06-20 11:30:36

    To prevent an outbreak of Legionnaires’ disease, the HSE’s ACOP L8 recommends that hot water in a building should be stored above 60°C and distributed above 50°C, and cold water distributed below 20°C.

  • What is Legionnaires’ disease?
    Question by: admin on 2018-06-20 11:15:34

    Legionnaires’ disease is a potentially fatal illness caused by the legionella bacterium, which may be present in tepid water and is spread by inhalation of fine water droplets or spray.

  • Is my MM2000 range thermometer still waterproof without its rubber boot?
    Question by: admin on 2018-06-19 15:34:49

    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.

  • What is a thermocouple thermometer?
    Question by: admin on 2018-06-18 13:22:07

    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

  • I regularly need to replace my thermometers and probes, can I set up a service contract to cover the cost?
    Question by: admin on 2018-06-18 12:41:03

    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.

  • I need a certificate of calibration for my thermometer, what should I do?
    Question by: admin on 2018-06-15 13:20:45

    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 our charges are: MM2000, MM7000, CA2005 and Solo Series of Handhelds = £35 The 4000, 5000 and 6000 Series of Large Display and Bench Instruments = £55 Your EHO might want you to have your thermometer re-calibrated yearly.
