Introduction:
Class I Standard Platinum Rhodium 10-Platinum Thermocouple (S) is a temperature measurement standard,has standard platinum-rhodium 10-platinum thermocouple and standard platinum-rhodium 30-platinum-rhodium 6 thermocouple two categories. Standard platinum-rhodium 10-platinum thermocouple is used in the temperature range of 419.527~1084.62℃ to achieve the value of thermocouple temperature transfer and precision temperature, accuracy grade has first-class standard and second-class standard. Standard platinum-rhodium 30-platinum-rhodium 6 thermocouple used in 1100~1500℃ temperature area thermocouple temperature value transfer and precision temperature, precision grade has second standard.
