PRODUCT DETAIL

Platinum and rhodium thermocouple commonly known as S-type thermocouple or precious metal thermocouples. Thermocouple series has the advantages of high accurate, best stability, wide-temperature range, long life. long-term maximum temperature range is 0~1300 ℃, short-term maximum temperature range is 0~ 1600 ℃.

Specification:
1.S type thermocouple
2.Tempe.range:0~1600C/1800C
3.probe size:customized
4.Protectiontube:Corundum&310S

Information
Type S thermocouples are constructed using one wire of 90% Platinum and 10% Rhodium (the positive or “+” wire) and a second wire of 100% platinum (the negative or “-” wire). Like type R, type S thermocouples are used up to 1600 °C. In particular, type S is used as the standard of calibration for the melting point of gold (1064.43 °C).
Type B thermocouples use a platinum–rhodium alloy for each conductor. One conductor contains 30% rhodium while the other conductor contains 6% rhodium. These thermocouples are suited for use at up to 1800 °C. Type B thermocouples produce the same output at 0 °C and 42 °C, limiting their use below about 50 °C.
