Sensor Requirements For Monitoring -80C Freezers

« Go Back


When you need to monitor -80C or below freezers, we recommend our Expanded Range Sensor (AC-TMPEXRJ12).

The AC-TMPEXRJ12 is an expanded range temperature sensor that can measure temperatures from -200C to +200C (-328F to +392F). Compatible with TempAlert WiFi and Cellular Edition devices, the Class A RTD temperature sensor is encased with a diameter of 4 mm and length of 150 mm stainless steel (316) sheath and wired with high temperature rated teflon cable protected by a stainless steel braid. The included cable length is 6'. Longer lengths are available - please contact us for details.

NIST certification/calibration available.
To use the sensor, plug the RJ-12 connection into any of the ports on your device. The tip of the sensor should be located in the monitored area. Keep the tip away from anything that could interfere with the readings (e.g. fan, high powered light).
