Monnit wireless high temperature sensor use an RTD to accurately measure temperatures from -50°C to +370°C. Perfect for high temperature critical applications such as ovens, heaters, furnaces and boilers. User customization allows you to set the frequency of sensor readings and create notifications from the system when certain criteria have been met or exceeded.
The High Temperature Sensor is not meant for wet, damp, high humidity environments. This sensor should only be operated in dry, low humidity environments. Should you need a temperature sensor that operates at extreme temperatures and can withstand getting wet or condensed on, please consider our Thermocouple Sensors.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
