Product Description
S type thermocouple wire platinum wire 99.99%
Type R, S, and B thermocouple wires are "Noble Metal" thermocouples, which are used in high temperature applications.
Type S thermocouple wires 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 wire (S/B/R TYPE)
Platinum Rhodium Assembling Type Thermocouple wire 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.
Application of thermocouple wire
• Heating - Gas burners for ovens
