S type B type R type thermocouple wire 0.35mm 0.5mm price
Product Description
Tankii 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 type (J,K,E, N,T,)
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).
Tankii 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%
Application of thermocouple wire
• Heating - Gas burners for ovens
• Cooling - Freezers
• Engine protection - Temperatures and surface temperatures
• High temperature control - Iron casting
