Monnit wireless low temperature sensors use an RTD to accurately measure temperatures from -200°C to +162°C. Perfect for low temperature critical applications such as freezers and coolers. 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 Low 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. Available with NIST traceable certificate good or 13 months.
