Thermocouple Theory - Pyromation

Refractory Metal Thermocouples Refractory Metal Thermocouples are the last category of thermocouple that Pyromation manufactures. These thermocouples are made of the exotic metals Tungsten and Rhenium, which are expensive, difficult to manufacture, brittle, and must be handled carefully. There are three types of refractory metal thermocouples:
