The Wireless Temperature sensor W56 measures temperature in the range between -40 °C to 125 °C. It is a general-purpose temperature sensor that can be used to measure temperature in liquids (water, mild acidic solutions) and air. The stainless-steel tube has a length of 195 mm.

The sensor can be used wirelessly via Bluetooth or wired via USB. The sensor is equipped with an OLED color display which shows some sensor information and the measured by the sensor values. This makes the sensor suitable to use as an independent measuring instrument.

The sensor can be used wirelessly via Bluetooth or wired via USB with the Coach or Coach Lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).
