WebGenerally, annual calibration is advised for every thermocouple. However, for thermocouples that see constant use, calibration should be made at shorter intervals. With constant use, the efficacy of the thermocouple deteriorates over time. So it is important that calibration should be made to ensure that the thermocouple works smoothly. WebThermocouples are a type of sensor used for the measurement of temperature. Thermocouples use the Seebeck effect, discovered by Thomas Johann Seebeck in the early 1800s. He was able to prove that if two dissimilar electrical conductors have a temperature differential across them, then a voltage difference is produced.
