ETI Legionnaires' Thermometer Kit

The ETI Legionnaires Kit is suitable for controlling and monitoring the temperature of standing water and other surfaces.  The kit includes three different probes, the Therma 1 thermometer, a countdown timer and a tub of wipes.  This is all housed in an ABS carrying case.

The choice of probes allows you to measure on various surfaces.  The ribbon surface probe can be used to take the temperature of tanks and pipes.  The wire probe is designed to measure hard-to-reach or awkward places where the other probes aren’t suitable and the penetration probe (immersion probe) is suitable for measuring water to a minimum depth of 25mm.

Controlling legionella bacteria means storing water below 20°C if it is cold, or above 60°C and distributed at above 50°C, if hot.  Bacteria will multiply in water between 20°C and 45°C and this is more likely to occur if nutrients such as scale, rust, sludge and algae are present.

The HSE provide guidance on the control of legionella bacteria in water.  If you are an employer, or in charge of a premises, you are responsible for organising the risk assessment.  The Approved Code of Practice (ACOP) applies to all hot and cold water systems in the workplace, regardless of capacity.

You must take action according to the readings you receive with your Legionnaires’ Kit and act in accordance to the Approved Code of Practice: Legionnaires Disease.
