Description / Features / Spec


ETI Legionnaires' Thermometer Kit

Use the Legionnaires’ Thermometer Kit from ETI to monitor and test the temperature of both standing water and the surface of pipes and tanks that form part of a water system.  The kit includes an immersion probe, ribbon surface probe, wire probe and traceable certificate of calibration.

The immersion probe can be placed in the water to a minimum depth of 25mm.  The ribbon surface probe may be used to take the temperature of pipes and tanks, and the wire probe can be used to reach awkward places or where the use of other probes may not be appropriate.

Incorrect water temperature is a risk factor for the growth for legionella, allowing bacteria to multiply in water with temperatures between 20 to 45°C. This is more likely to occur if a supply of nutrients is present, such as scale, rust, sludge or algae.  To control legionella bacteria water should be stored below 20°C if it is cold or above 60°C and distributed at above 50°C if hot.

The revised Approved Code of Practice (ACOP) issues by the Government’s Health and Safety Executive (HSE) significantly extends the scope of its guidance on the control of legionella bacteria in water.  This means employers or those in charge of a premise are responsible for organising a risk assessment.  This code applies to all hot and cold water systems in the workplace, regardless of their capacity.  The lower limit of 300L previously used to exclude domestic systems but this no longer applies. 

This code only applies to risk arising from a work activity; it does not apply to domestic systems which may represent a risk.  Please be aware that all employers who manage premises with hot/cold water systems and/or a wet cooling system have a legal responsibility to identify any risk of contamination and to prevent or control it.
