  • Hardness Adjustment: We supply platinum-rhodium wire in soft (electrically annealed) or semi-hardened forms based on customer requirements.

Type B Platinum Rhodium Thermocouple Wire Features

  • High Accuracy: Known for its exceptional accuracy and stability among thermocouples.
  • Wide Temperature Range: Measures temperatures from 0°C to 1800°C.
  • Long Service Life: Offers a longer lifespan compared to other thermocouples.
  • High Temperature Limit: Suitable for high-temperature applications up to 1800°C.
  • Low Thermoelectric Potential: Minimal effect from reference junction temperature changes, no need for compensating wires.
  • Durability: Ideal for use in oxidizing and neutral atmospheres, short-term use in vacuum, but not in reducing or metal/non-metal vapor environments.
  • Resistance to Degradation: Rhodium improves heat resistance and reduces degradation from high-temperature diffusion.
  • Stability: Small grain size and increased rhodium content enhance thermoelectric stability and mechanical strength.

Type B Platinum Rhodium Thermocouple Wire Applications

  • Glass and Ceramics Industry: Used for furnace temperature measurements to ensure product quality and production efficiency.
  • Steel and Non-Ferrous Metal Smelting: Used for temperature control during the smelting process to optimize smelting techniques.
  • Burners and Boilers: Monitors the temperature of burners and boilers to ensure safe operation.
  • Automotive Exhaust Measurement: Used to measure the temperature of automotive exhaust gases to assess emission performance.
  • Scientific Research: Monitors high-temperature reactions in research, providing accurate temperature data support.

Type B Platinum Rhodium Thermocouple Wire Packaging

Type B Platinum Rhodium Thermocouple Wire is carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
