B
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.
