Product Description

0.5mm PTFE Type B  Platinum Rhodium Thermocouple Bare Wire 0


  • Thermocouple Wire

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 R, S, and B thermocouples are "Noble Metal" thermocouples, which are used in high temperature applications.

Type S thermocouples are characterized by a high degree of chemical inertness and stability at high temperatures. Often used as a standard for calibration of base metal thermocouples.

Platinum rhodium thermocouple(S/B/R TYPE)

Platinum Rhodium Assembling Type Thermocouple is widely used in production places with high temperature. It is mainly used to measure temperature in glass and ceramic industry and industrial salting.

Insulation material: PVC, PTFE, FB or as per the customer's requirement.


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%


Consideration for bare wire type B thermocouple applications:


  • Heating - Gas burners for ovens
  • Cooling - Freezers
  • Engine protection - Temperatures and surface temperatures
  • High temperature control - Iron casting
