The MP-TS3 has been designed for ambient temperature detection with an LCD display and an isolator switch With a sensitive temperature response of ±0.5 °C and a wide temperature range of -40 to +125 °C (thermocouple) and -30°C - 60°C (sensor) it is the perfect sensor for fridge and freezer temperature monitoring and other ambient temperature recording applications. The MP-TS3 uses the 920Mhz frequency and Lora protocol which has an ultra-long-range transmission range of up to 500 meters from the MP-WH2 Wireless Hub*. The built-in 3500mAh /3.6V battery gives up to 3 years of operation (depending on operating conditions). The Monitor Pro wireless temperature detection solution integrates seamlessly with Safe Food Pro’s Digital Food Control Plan software. NOTE: To operate this device requires a Safe Food Pro software subscription for either Professional or Multi-Site subscriptions.

Calibration is best checked by comparing sensor data to a thermometer temperature reading using a glass of water that has been in the fridge for at least 2 hours (or ice pick method for freezer). If a sensor is not reading within ±0.5 °C deviation return to MonitorPro for repair under 1 year warranty.
