Type S Thermocouple

The S-type thermocouple, also known as the single platinum-rhodium thermocouple, belongs to the category of precious metal thermocouples. The nominal chemical composition of its positive pole (SP) is a platinum-rhodium alloy containing 10% rhodium and 90% platinum, and the negative pole (SN) is pure platinum. The standard diameter of the couple wire is 0.5mm, and the allowable deviation is -0.015mm. This thermocouple, with its unique material properties, can accurately sense temperature changes and convert them into electrical signals for output, providing reliable data for temperature measurement.
