Tankii ISO certified Platinum rhodium alloy thermocouple wire used for steel
Product Description
Platinum Rhodium Alloys with more than 20% Rh are insoluble in aqua regia. Mainly used as thermocouple materials, such as PtRh10/Pt, PtRh13/Pt, etc.,used as thermocouple wires in thermocouples to directly measure or control the temperature of fluids, steam, gas media, and solid surfaces within the range of 0-1800 ºC in various production processes.
Tankii Thermocouple wires are selected based on the temperature range, accuracy, and environmental conditions of the application.
Thermocouple wires are commonly used in industries such as manufacturing, HVAC, and scientific research.
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
• Cooling - Freezers
• Engine protection - Temperatures and surface temperatures
• High temperature control - Iron casting
