The CS200 CONTROL SYSTEM uses a Type T thermocouple to measure temperature within the Cryostorage freezer. The temperature curve for a thermocouple is nonlinear so it is important that the CS200 CONTROL SYSTEM have a good calibration to provide accurate temperature readings. The temperature is traceable to the National Institute of Standards and Technology (NIST) ITS-90 Thermocouple Database. -
