Mineral insulated cable type k,j,t,e thermocouple mi cable
Description:
There are multiple types and grades of thermocouple wire.Each type of thermocouple wire has a specific combination of metal alloys.This combination is what defines the type of thermocouple.Thermocouple grade wire is used to manufacture thermocouple probes.Thermocouple grade wire is normally used for the junction and inside the stem sheath.
