Legionella Advice on Hard to Reach Temperature Points

Wednesday, 10 April 2013 21:27:25 Europe/London

Hard to reach? Legionella experts launch new solution to problem temperature points

Facilities and premises managers faced with the problem of monitoring hard to reach water temperature points now have the ideal solution thanks to a handy new device from TM Electronics, market leaders in temperature measurement for legionella risk management.

The new TC Wall Port helps tackle the hidden risks presented by outlets which are difficult to access - boxed-in TMV’s, concealed pipework and covered water tanks. These outlets need to be monitored regularly to ensure safe water temperatures are being maintained.

What is a TC Wall Port?

The new device is a thermocouple temperature sensor monitoring point which can be conveniently mounted to facilitate spot checks on any test point with difficult or impaired access. The port is designed for use with fine wire probes which are attached to the temperature test point and left in-situ. These wires are then run to the port – a wall-mounted, small white box measuring just 52 x 52mm. This allows temperatures to be taken by simply ‘plugging’ a standard thermocouple thermometer into the wall port – much easier and less time-consuming than dismantling boxing below sinks or using ladders to access covered tanks, necessitating working at height.  

Main Applications

  • Boxed-in TMVs – no need to access the valve each time to check hot water temperature.
  • Pipework including boiler flow and return points.
  • Water Storage Tanks (with special immersion probe)
  • High-level test points - avoid using ladders and Working at Height restrictions.
  • Remote measurement of cold storage, environmentally sensitive rooms or hazardous areas.


The new device can be used with other thermocouple sensors such as the company’s Velcro, Magnetic, Rubber Patch and Immersion Probes. Also, the front cover is recessed to take an ID or barcode label for use with the company’s MM7000 Bluetooth Barcode logging thermometer if required.

Trust the experts

The TC Wall Port is the most recent in a range of innovative products developed specifically by TM Electronics to support water temperature monitoring, and remote monitoring of sensitive or hazardous environments. The company leads the field in producing robust, waterproof equipment and portable kits to improve on reliability and convenience.

Best Sellers

Water hygiene companies and facilities and estates managers particularly like:

  • MM7000 - barcode-scanning thermometer, which can record and download not only temperature, time and date but also the unique location of every pipe, tap or calorifier tested.
  • Dual Purpose Surface/Immersion probe – all-in-one running water and pipe surface testing
  • Affordable fine wire sensors - can be ordered in bespoke lengths up to 20 metres.

“Listening to those at the sharp end of water temperature monitoring, has enabled us to come up with designs that solve actual problems experienced on the ground,” says MD, Tom Sensier. For example, our dual purpose surface/immersion probe routinely halves the time required on site and our MM2000 thermometers are so robust they last for years – and I mean that literally: the current record is 17 years and counting!”

Did You Know?

To prevent an outbreak of Legionnaires’ disease, hot water in a building should be stored above 60°C and distributed above 50°C, and cold water distributed below 20°C. Older buildings, facilities with a large number of water outlets and accommodation used by vulnerable groups like the elderly or people with a reduced or impaired immune system are those which present the most risk.
