Second class standard platinum rhodium 30 platinum rhodium 6 thermocouple

The second-class standard platinum rhodium 30 platinum rhodium 6 thermocouple is mainly used as a standard for temperature value transmission in the temperature range of 1100-1500 ℃. The second-class standard platinum rhodium 30 platinum rhodium 6 thermocouple is also used for precision temperature measurement in this temperature range. The second-class standard platinum rhodium 30 platinum rhodium 6 thermocouple (hereinafter referred to as the standard double platinum rhodium thermocouple) has a positive electrode (BP) of a platinum rhodium alloy containing 30% rhodium and a negative electrode (BN) of a platinum rhodium alloy containing 6% rhodium.
