What two metals are in a thermocouple?

The base metal thermocouples, known as types E, J, K, T, and N, have higher sensibilities than the noble metal. They comprise the most commonly used category of thermocouple and the conductor materials in base metal thermocouples are made of common and inexpensive metals such as nickel, copper, and iron.

Thermocouple Introduction and theory

(Type T) thermocouple and look at the voltage output: We would like the voltmeter to read only V 1, but by connecting the voltmeter in an attempt to measure the output of Junction J 1, we have created two more metallic junctions: J 2 and J 3. Since J 3 is a coppertocopper junction, it creates no thermal EMF (V 3 = 0), but J 2 is a coppertoconstantan junction which will add an EMF (V 2) in ...
