Legionella Thermometers

In the UK, a legionnaires' risk assessment is a legal requirement for businesses to help prevent the growth of Legionella bacteria. This harmful bacteria thrives in water temperatures between 20 °C and 45 °C, making accurate monitoring essential.

At ETI, we offer a range of legionella thermometer kits and water thermometers specifically designed to ensure safe water temperatures. Our kits make it simple to measure and record legionella temperatures, helping you stay compliant with regulations and minimise risk.

Explore our range to discover reliable, easy-to-use tools to ensure safe hot and cold water systems.
