What is a platinum rhodium 13 - Platinum rhodium thermocouple? Platinum rhodium - 13 Platinum rhodium thermocouple is extremely containing rhodium platinum rhodium ( RP) , very pure platinum (negative RN）。 With S type thermocouple, the thermoelectric emfs rate is about 15%, other functions are basically the same.

this kind of thermocouple in the Japanese property, as a high temperature thermocouple used much, but the Japanese industrial skill before 1981 specification ( JIS） Rhodium platinum rhodium content of 12. 8%, R type thermocouple compared with the current, under 1550 ℃, its low thermoelectric emfs about 100 mu of V, which please note. In recovery, vacuum or containing metal vapor under the premise of using, are to be contaminated. Long time use ordinary temperature should not exceed 1400 ℃.
