High quality platinum bare thermocouple wire type S, R with noble metal

Type S, Pt10%Rh-Pt thermocouple is a thermocouple junction often used for extreme high temperatures. Type S, Pt10%Rh-Pt shares a lot of characteristics with type R, Pt13%Rh-Pt thermocouple, but type R has a higher Seebeck coefficient than type S. Temperature range of type S, Pt10%Rh-Pt thermocouple wire is 0°C to +1600°C.

The thermocouple type S is designed for continuous use in oxidizing or inert atmospheres at temperatures up to 1600°C and can withstand brief periods up to 1700°C. Prolonged exposure to high temperatures can cause degradation of the thermocouple, including the possibility of rhodium diffusion into the pure platinum conductor, which results in a reduction in output. Therefore, it’s important to be aware of potential embrittlement caused by the environment.
