The miniature Pd-C eutectic cell (1492 °C) for thermocouple self-calibration has been studied to transform the reliability of thermoelectric performance of the Type C thermocouple by facilitating in-situ calibration without need forremoval sensor for recalibration.

The accuracy of high temperature measurement is significant in terms of: reducing product waste, minimizing energy consumption and promoting health and safety.

Thermocouples are the most widely used temperature sensor for high temperature measurement.
