Testing for Legionella with the ETI 860-860 Legionella Testing Kit

By law, as defined in the revised Approved Code of Practice (ACOP) issued by the Government's Health and Safety Executive (HSE), 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 ETI is excellent for helping to prevent the spread of this 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 probes can be used as follows:

• Insert the immersion probe into the water to a minimum depth of 25mm to test the overall temperature
• Use the ribbon surface probe to take the surface temperature of pipes and tanks
• Use the wire probe to reach spots where other probes simply won't fit

About the ETI 221-041 Therma Differential Digital Thermometer

With the ETI Therma Differential thermometer you can plug two probes in at the same time and compare temperature measurement between two different points!

When testing for Legionella, doing this will allow you to compare different parts of the water system to ensure water is being stored at the right temperature. Using the thermometer is simple - just plug in the included probes and start testing!

For added convenience the ETI Therma Differential is even fully waterproof and is rated to IP66 and IP67.

Key features of this product include:

• Dual-input thermometer - measure temperature from two points simultaneously
• Works with a wide variety of interchangeable type K temperature probes (sold separately)
• Ideal for HVAC work - measure the temperature drop across radiators or the temperature rise and fall of other objects
• Measure from each channel individually (T1 or T2) or measure the difference (T1-T2)
• Temperature measurements from -99.9 to 299.9°C with resolution of 0.1°C and 300 to 1372°C with resolution of 1°C
• Data hold function temporarily stores current values shown on the screen
• MAX/MIN mode calculates the maximum and minimum temperatures taken over a period of time
• Automatic power off helps to save battery life
• 7500 hour battery life on 3 x 1.5V AAA batteries
• IP66 and IP67 rated waterproof case
• 2 year guarantee from ETI
