Testing for Legionella with the Comark Legionella Testing Kit

Current law concerning Legionella water temperature testing, as defined in the revised Approved Code of Practice (ACOP) issued by the Government's Health and Safety Executive (HSE),states that it is the responsibility of all employers, who manage premises with hot/cold water systems and/or a wet cooling systems, to prevent Legionella contamination and to prevent or control its spread.

This kit from Comark is designed to help prevent the spread of the Legionnaires type of bacteria. Generally, Legionella bacteria start to multiply in water at temperatures between 20 to 45°C (with the spread increased by the presence of nutrients such as rust, algae, sludge and scale). To control this, water should typically be kept cold below 20°C while hot water should be stored above 60°C and distributed at 50°C.

You can use this kit to test the water in storage as well as test the surface of pipes and tanks in the water system.

The KM330 Legionella Kit contains a KM330 rugged Type K Thermocouple thermometer, Pro 1 Penetration Probe and SK21M Surface Probe and a soft carry case.

Ideal for a range of industrial uses, including air conditioning temperature monitoring and heating system testing.

Features include:

  • Selectable 0.1°/1° resolution
  • Displays temperature in °C or °F
  • Maximum temperature memory, hold function to freeze displayed reading.
  • Protective slip-on boot with desk stand.
  • Sub-miniature connector

KM330 Industrial Thermometer is a single input thermometer with a wide range of applications. Users can select readings in °C of °F and high or standard resolution to suit their requirements. Hold and Max functions are provided, to freeze the last reading on the display and to record the maximum value.

  1. Excellent value and service

    Posted by David S on 19th May 2020

    Customer service was excellent and fast delivery. Device is compact but feels sturdy. Easy to use. It came with full calibration as requested.

  2. Just what I required!

    Posted by David on 12th Oct 2016

    Purchased for legionella temperature testing at a GP surgery. Comes with a black soft case; keeping instrument safe and together with the probes. The unit itself has a rubber protective sleeve. In use it reacts quickly and has a useful Max and hold function that makes recording that much easier. Would recommend, seems good value.
