Hygienic design

Maintaining a hygienic catering thermometer probe is essential for food businesses. The Thermapen ONE Bluetooth thermometer's casing includes Polygiene BioMaster product protection to reduce bacterial growth. It is also fully waterproof to IP67, enabling it to be submerged in water for thorough cleaning.

Folding probe

Folding instant-read thermometers are ideal for protecting your probe from damage while making it easy to transport and keep on hand throughout the day. This Bluetooth food thermometer features a reduced tip, stainless steel penetration probe that rotates 180° and folds into the side of the instrument for safe storage. 

How to use the Thermapen ONE Bluetooth thermometer

To use the Thermapen ONE Bluetooth thermometer, simply pair it with your device (iOS or Android), probe the item to be measured and press the button to transmit your temperature data. The thermometer will show a ‘PASS’ or ‘FAIL’ response depending on whether the temperature recorded is within the item’s set limits. View and manage your temperature readings using your custom software. 

Custom software available

A Software Developer Kit (SDK) is available upon request to allow integrators to write custom apps to communicate with the Thermapen ONE Blue. Free end-to-end technical support is available. 

Please Note: New display features are only available when using the latest Software Development Kit. BLE 5.0 thermometers have a range of 50 metres depending on the user's smart device make and model. Environmental conditions may also affect signal strength.

Safety checks digitised

Exceed HACCP compliance with a digital food safety system. Bluetooth thermometers ensure every temperature reading is taken correctly and on time. Plus, they create a data system that is organised, accessible, and easy to analyse and share. 


The Thermapen ONE Blue makes HACCP checks quick and easy to complete. The easy one-button operation means little training is required. Users can work through checklists of items on-screen, viewing the name of the item to be measured and the required temperature range before receiving pass/fail feedback. Integrate the product into your food safety software to customise your checks. 


Not only will choosing the Thermapen ONE Blue create a more accurate and reliable data archive, but it will also save time spent manually recording temperatures. This time can be re-invested into other areas, enabling a more productive and efficient business model.
