New test port for schools simplifies legionella monitoring and prevents vandalism.

Help is on hand for schools premises managers responsible for monitoring water temperature points in public areas which are traditionally concealed or positioned at height to satisfy health and safety, for cosmetic reasons or to prevent vandalism or tampering.

Temperature experts, TM Electronics (UK) Ltd now offer the TC Wall Port, a low-cost accessory which allows discrete fine wire sensors to monitor boxed-in TMV’s, concealed pipes and covered water tanks up to 20 meters away. 

What is a TC Wall Port?  The new test port – measuring just 52 x 52 mm - is actually a temperature sensor monitoring point which facilitates spot checks on any water outlet with difficult or impaired access. This allows temperatures to be taken by simply ‘plugging’ in a standard thermocouple thermometer to tiny fine wire sensors. A much simpler solution than dismantling boxing below sinks or using ladders to access covered tanks necessitating working at height.

How does it work? -  The TC Wall Port is primarily designed for use with fine wire probes which are attached to the temperature test point and left in-situ. These wires (available in a variety of lengths) can then be fitted into conduits or run neatly to the test port which is screwed to the wall, providing an unobtrusive and easy to install solution. Alternatively, it can also be used with a wide range of surface, clamp or immersion probes. 

Paperless recording - For premises and facilities managers adopting a paperless recording system, less vulnerable to human error, the front cover of the test port is recessed to take an ID or barcode label for use with the company’s MM7000 Bluetooth Barcode logging thermometer.

TM Electronics MD, Tom Sensier, says: “The TC Wall Port is as small and unobtrusive as a phone socket but its’ simple yet efficient functionality is already making a big difference to legionella risk management wherever it is used.”

What’s a safe water temperature?  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. Water outlets must be monitored – typically once a month – to ensure safe water temperatures. Older buildings; facilities like schools, hospitals, leisure facilities or offices which have a large number of water outlets; and accommodation used by those with impaired immune systems, are the kind of premises which present the most risk.    


Trust the experts – With over 20 years’ experience, TME are market leaders in temperature measurement equipment for the prevention of Legionnaires’ disease, specializing in accurate, fast response thermometers and sensors which are robust and waterproof.
