Abstract :
The Co-C cells to realize the metal-carbon eutectic points were constructed, and the uncertainty of the Co-C eutectic point was evaluated using Pt/Pd thermocouples. The uncertainty of Pt/Pd thermocouple calibration at the Co-C eutectic point was estimated to be 0.53 K (k = 2), including the uncertainty of the measuring system and the drift of thermocouple. This result shows the appropriateness of the device for calibrating thermocouples.
