WRP-120 platinum rhodium thermocouple

A thermocouple consists of two dissimilar metals joined together at one end. When the junction of the two metals be cooled or heated and a voltage is produced that can be correlated back to the emperature. The calibrations are K, N, E.J, T, S, R, B. Each calibration has a different temperature range.S R B type thermocouple is applicable to oxidation and inert atmosphere can also be used for short-term vacuum, but does not apply to restore an atmosphere of or containing metal or non-metallic vapor in the atmosphere. The temperature range of thermocouple type s is 0 to 1800℃
