Calibration Thermodynamic – Temperature
Thermodynamic fixed-point calibration: The thermodynamic fixed point calibration is the most accurate way to calibrate a thermocouple. This method involves comparing the thermocouple’s temperature readings against the globally accepted, fixed temperature points of common elements and compounds where their physical state changes.
Temperature calibration refers to the calibration of any device used in a system that measures temperature. Most importantly, this usually means the temperature sensor, itself, which is typically a platinum resistance thermometer (PRT or PT-100), thermistor, or thermocouple.
