Standard Thermocouple C820

C820 is a standard thermocouple that uses high-purity platinum (positive leg) and palladium (negative leg) and was commercialized through technology transfer from the National Institute of Advanced Industrial Science and Technology (AIST).
Compared to conventional thermocouples that use precious metal thermocouples (R, S, B) specified by the JIS, stability at high temperatures is significantly improved.

Improved stability at high temperatures

MODEL C820 is designed as a standard thermocouple for calibrating thermometers. The reference electromotive force value is ASTM Vol.14.03 E1751.
