1. Homogeneous conductor law
A closed loop is formed by welding two ends of the same homogeneous material (conductor or semiconductor). No matter how the conductor cross section and temperature distribution, no contact potential will be generated, the thermoelectric potential will offset, and the total potential in the loop will be zero.

2. Law of intermediate conductor
The intermediate conductor (the third conductor) is connected to the thermocouple circuit. As long as the temperature at both ends of the intermediate conductor is the same, the introduction of the intermediate conductor has no effect on the total potential of the thermocouple circuit, which is the intermediate conductor law.

3. Law of intermediate temperature
The thermoelectric potential between the two contacts (temperature T, t0) of the thermocouple circuit is equal to the algebraic sum of the thermoelectric potential of the thermocouple when the temperature is t, TN and the thermoelectric potential when the temperature is TN, t0. TN is the intermediate temperature.

4. Law of reference electrode
This law is only studied and concerned by professionals. Generally, people in production and use do not understand it. The simple explanation is: use high-purity platinum wire as standard electrode. Suppose that the positive and negative electrodes of nickel chromium nickel chromium thermocouple are paired with the standard electrode respectively, and the sum of their values is equal to the value of this nickel chromium nickel chromium thermocouple.
