Type B Thermocouple (Platinum Rhodium – 30% / Platinum Rhodium – 6%):
The Type B thermocouple is used in extremely high temperature applications. It has the highest temperature limit of all of the thermocouples listed above. It maintains a high level of accuracy and stability at very high temperatures. The type B has a lower output than the other noble metals (type R & type S) at temperatures below 1,112F (600C).
Type B Temperature Range:
Thermocouple grade wire, 32 to 3100F (0 to 1700C)
Extension wire, 32 to 212F (0 to 100C)
Accuracy (whichever is greater):
Standard: +/- 0.5%
Special Limits of Error: +/- 0.25%
