Wire And Thermocouple Extension Wire
- Thermocouple Extension Wire
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.
