Thermocouple Wire (Type S, R, B, Platinel)

Premium thermocouple wires designed for accurate, stable temperature sensing in high-temperature industrial environments.

Our thermocouple wires are engineered for superior thermal measurement in demanding industrial settings. These include Type S, R, and B thermocouples—renowned for their stability at temperatures from 1400°C to 1750°C—and Platinel thermocouples, which offer increased service life and enhanced calibration stability. 

Manufactured in single batches for performance consistency, the wires are calibrated to ISA, ANSI, or IEC standards, ensuring accuracy within ±0.25% between 400°C and 1450°C. Industries rely on these wires in continuous process control, metallurgy, chemical production, and beyond.

  • High-temperature capability up to 1750°C

  • Precision calibration per international standards

  • Long-term stability and low drift

  • Single-batch wire production for uniform performance

  • Recycling and metal reclamation options

Thermocouple Wire Specifications

Type S Pt vs. Pt 10 Rh: 

One of the most popular and widely used precious metal thermocouple combinations is known for its high accuracy over a broad temperature range. The combination has excellent mechanical and chemical properties, low electrical resistivity, and is readily obtainable in uniform quality and in very fine diameters.

Type R: Pt vs. Pt 13 R

This widely used combination is almost identical to Type S except for a slightly higher thermoelectric output, which accommodates instruments that have been calibrated for this output.

Type B: Pt 6 Rh vs. Pt 30 Rh

This widely used thermocouple is very similar to other Pt and Rh combinations. It performs well at the higher application temperatures where other combinations may be subject to accelerated drift or physical degradation. It is unique in that, at reference junction temperatures below 100° C, compensating lead wire is generally not necessary: plain copper conductors are adequate.

Platinel®

A development by BASF ECMS that brings together the high electrical output of the high base alloys with the oxidation resistance and stability of the precious metals. Often used as a direct replacement for Type K in process control applications where long life, stability, and continuous trouble-free performance is required.

Accuracy: ±0.25% from 400°C to 1450°C
Batch Quality: Single-source batch manufacturing ensures performance consistency
Compliance: Meets ISA, ANSI, IEC calibration standards

Applications

Designed for industrial operations where reliable high-temperature measurement is critical.
1
Metal Processing
Thermocouples monitor furnace and crucible temperatures to optimize metal quality and energy use.
2
Semiconductor Manufacturing
High-purity thermocouple wire supports accurate wafer processing and doping operations.

Sustainability Through Metal Recovery

BASF ECMS offers end-of-life recycling programs for thermocouple wire, reclaiming precious metals like platinum and rhodium. Customers can receive monetary value or credit toward future wire purchases. This program supports circularity and cost-efficiency in metal-intensive industries.
