The material temperature sensor has an operating temperature range of 0 ºC - 55 ºC. It is supplied with a 5 m long XC sensor cable. Cables can be coupled together for increased overall length up to 60 m. A calibration certificate is supplied with the sensor. Note: Up to three material temperature sensors can be attached to the XC-80 compensator to allow linear measurements to be normalised to a standard material temperature of 20 ºC.
