Precious metals

Precious metal thermocouples are typically applied in high temperature environments to measure temperatures up to 1850°C. These thermocouples are known for being strongly resistant to corrosion and are characterized by their long life cycle and high accuracy. Depending on the application, thermocouple wires of different kinds of precious metals are used. Examples are (an alloy of) platinum, rhodium, and iridium.

Kamet supplies the highest quality precious metal wires for thermocouples, in all available diameters, lengths, and alloys.

Kamet has a stock of standard grade thermocouple wire type R, S, and B. We offer our stock in customized quantities, with no minimum length required. Additionally, special limits wire is offered in a variety of materials and diameters, produced with especially tight tolerances. All our thermocouple wires are certified is an accredited calibration lab, meeting international standards.

Thermocouple wire type B, R, and S

Thermocouple wires are supplied as two single conductor, uninsulated wires. The matched pairs usually consist of alloys of platinum and rhodium and perform well in continuous oxidizing environments. Especially thermocouple type R and S are excellent in oxidizing or inert atmospheres up to 1400 °C. To accurately measure temperatures up to 1700°C, thermocouple type B is recommended.

Refining / recycling service

Kamet offers an advantageous recycling service to refine precious metals from used products.


With the different types of thermocouple wires, thermocouples are customized to perform best in a variety of industries, such as the glass, metal, or semiconductor industry.

Precious metal wires and custom made products

Wires and custom made products from precious metals, such as platinum, gold, silver, rhodium, and iridium can be supplied in all shapes, sizes, and alloys.
