Type S Thermocouple (Platinum Rhodium - 10% / Platinum): The Type S is used in very high temperature applications. It is commonly found in the BioTech and Pharmaceutical industries. It is sometimes used in lower temperature applications because of its high accuracy and stability. The type S is often used with a ceramic protection tube. 

Type S Temperature Range:


• Maximum continuous operating temperature: up to 2,912F (1600C)

• Short term use: up to 3,092F (1,700C)

• Thermocouple grade wire, -58 to 2700F (-50 to 1480C)

• Extension wire, 32 to 392F (0 to 200C)




• Accuracy (whichever is greater):




• Standard: +/- 1.5C or +/- .25%

• Special Limits of Error: +/- 0.6C or 0.1%




• Consideration for bare wire type J thermocouple applications:

• The Type S can be used in inert and oxidizing atmospheres up to 2,912F (1600C) continuously and up 3,092F (1,700C) for short term use.
