Premium Bluetooth Legionella Thermometer Kit

Incorrect water temperature is a key risk factor for Legionella growth. The Legionella bacteria multiply in water at temperatures between 20 to 45 °C, particularly if a supply of nutrients is present, such as scale, rust, sludge or algae.

A typical method of control is to store cold water below 20 °C. Hot water should be stored above 60 °C and distributed at above 50 °C. Regular testing using a water temperature thermometer helps control legionella risks.

Current legislation means that you must organise a risk assessment if you are an employer or person in control of premises. The revised Approved Code of Practice (ACOP) issued by the Government's Health and Safety Executive (HSE) significantly extends the scope of its guidance on controlling legionella bacteria in water.

The code now applies to all workplace hot and cold water systems regardless of their capacity; the lower limit of 300 litres previously used to exclude domestic systems no longer applies. Whilst domestic systems may represent a risk, the code only applies to risk arising from work activity.

This means all employers managing premises with hot/cold water systems or wet cooling systems are legally responsible for identifying contamination risks and preventing or controlling them.

This kit gives you smart technology alongside all the professional tools needed for water safety testing. Packed inside a hard carrying case, you get the Therma K Blue thermometer, three specific temperature probes, a countdown timer, and 100 anti-bacterial probe wipes. We also include a free traceable calibration certificate for your compiance records.

The Standard Bluetooth Legionella Thermometer Kit allows you to complete paperless risk assessments. Using Bluetooth, the Therma K Blue thermometer sends accurate temperature readings directly to your smartphone or tablet with a single tap. This eliminates the need for manual paperwork, reduces human error, and creates an instant, time-stamped digital log for your health and safety records.

No, there are no ongoing costs or subscription fees. The kit pairs with the free ThermaData Hub software and mobile app. Through the app, you can build custom checklists for your building, monitor your temperature results, and export the data easily. For larger businesses, a free SDK (Software Development Kit) is also available to integrate the thermometer with your own existing systems.

The Health and Safety Executive (HSE) says you must check your water often to follow the rules. Usually, you should test your hot and cold taps once a month. Hot water needs to reach 50 °C within one minute of turning on the tap. Cold water must drop below 20 °C within two minutes. Places with vulnerable people, like hospitals or care homes, must do daily checks on their main water outlets.

The Approved Code of Practice (ACoP L8) applies to all workplace hot and cold water systems, regardless of their capacity. Any employer, landlord, or facility manager overseeing premises with hot or cold water systems is legally responsible for identifying contamination risks and implementing a reliable temperature monitoring programme to control them.
