Therma 1 Digital Thermometer
At the heart of the kit is the dependable Therma 1 thermometer, engineered for fast, accurate temperature measurement across a wide operating range. Compatible with Type K thermocouple probes, it delivers consistent performance for a variety of water hygiene applications.
The thermometer also features a temperature hold function for easier recording of readings, while its automatic power-off feature helps maximise battery life. Under normal use, the battery can last for up to five years.
Two Probes for Greater Flexibility
The kit includes two purpose-designed probes to suit different inspection tasks.
The waterproof surface probe is ideal for checking the temperature of pipework, storage tanks and running water at outlets. Its flexible coiled lead makes it practical for routine monitoring.
The heavy-duty PTFE wire probe is designed for taking water temperature readings in more confined or difficult-to-access locations, making it suitable for a wide range of inspection environments.
Designed for Routine Legionella Testing
Regular temperature monitoring is one of the most effective ways to reduce the risk of Legionella bacteria developing within water systems. This kit enables maintenance teams and responsible persons to carry out routine temperature checks quickly and accurately across multiple outlets.
All equipment is supplied in a durable zip case, allowing you to keep everything organised and ready for site visits.
Why Water Temperature Matters
Legionella bacteria are most likely to multiply in water between 20°C and 45°C, particularly where nutrients such as sediment, scale, rust or biofilm are present.
Good water hygiene practice recommends maintaining:
- Cold water below 20°C
- Stored hot water above 60°C
- Hot water distributed at 50°C or above
Regular temperature monitoring helps identify potential risks before they become serious issues and forms an important part of an effective Legionella management plan.
Who Should Use a Legionella Thermometer Kit?
This kit is suitable for anyone responsible for managing water systems, including:
- Facilities managers
- Building maintenance teams
- Water hygiene contractors
- Landlords and letting agents
- Schools, hospitals and care homes
- Hotels, leisure centres and commercial premises
- Industrial facilities and offices
UK health and safety legislation requires duty holders to assess and manage the risk of Legionella where water systems are present. Accurate temperature monitoring is a fundamental part of demonstrating effective control measures and supporting ongoing compliance with current guidance.
Whether you‘re carrying out scheduled inspections or maintaining a comprehensive Legionella control programme, the ETI 860-885 Standard Legionella Thermometer Kit offers a practical, reliable solution for professional water temperature testing.
