Diameter 0.5mm 25 SWG platinum wire rhodium Thermocouple wire (Type SP/SN )

Type R, S, and B thermocouple wires are "Noble Metal" thermocouples, which are used in high temperature applications.
Type S thermocouple wire 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
• Cooling - Freezers
• Engine protection - Temperatures and surface temperatures
• High temperature control - Iron casting
