The ETI Waterproof Legionnaires’ or Legionella Thermometer Kit is a comprehensive testing solution tailored for monitoring water temperatures in hot and cold water systems,  a critical part of managing Legionella bacteria risks. Featuring a high-performance waterproof thermometer with 0.1 °C resolution and IP66/67 ingress protection, this kit enables reliable temperature measurement of standing water, pipe surfaces and tap water using its set of versatile probes.

Built for use in commercial, industrial and facilities management settings, the kit includes helpful accessories such as a water-resistant countdown timer, a carton of 100 single-sachet probe wipes and a protective ABS carry case — making it ideal for site visits, routine checks and compliance inspections under health and safety guidelines.

Key Uses & Applications

• Legionella risk assessments: Essential for temperature checks that help meet Legionella control regulations and reduce bacterial growth risk.
• Water system monitoring: Suitable for testing both standing water and surface temperatures on pipes and tanks within water systems.
• Facilities & maintenance teams: Ideal for building managers, risk assessors, estates personnel and HVAC technicians.
• Compliance & reporting: Supports formal documentation by providing traceable calibration and accurate readings where required.

Why It Matters

Legionella bacteria multiply in water between 20 °C and 45 °C, so accurate monitoring of water temperatures is critical to any risk assessment and control plan. This kit helps professionals measure temperatures reliably to help ensure cold water is stored below 20 °C and hot water is maintained above threshold levels that discourage bacterial growth.
