The BT125 Bluetooth Pocketherm is fast, accurate and waterproof. It is designed for use in the kitchen and other food production areas. The Bluetooth Pocketherm thermometer transmits temperature data via Bluetooth to your Android or iOS phone or tablet. The stainless-steel probe with a fast-responding 1.5mm tip folds out to allow you to choose the best angle to take different temperatures at different points in the kitchen such as prep, cooking or cooling.


Integrate the Pocketherm Bluetooth Thermometer using Comark API in to your Digital Management System and manage all your HACCP temperature recording. It’s a simple way to automate data collection and eliminates the need for handwritten temperature records.

Comark Bluetooth API

The Comark APIs enable a User Interface (App) to extract data such as temperature and humidity from the Pocketherm Bluetooth Thermometer and have it sent to the User Interface (App) to be displayed as results. The benefit of this approach is that you can bring large amounts of HACCP critical data from various devices, into a single platform, using a third-party program or software suite. This enables you to monitor manual tasks from product delivery to food storage, food preparation and foodservice. You can also incorporate real-time monitoring data for periodic checks of your storage and display units, thus freeing up valuable staff time to concentrate on more operational and quality tasks.

In order to use the Comark API’s you will of course need a User Interface (App) or Software Suite.
