Question
Do all the thermocouples have a neutral temperature?

Answer

As neutral temperature is The temperature of the hot junction of a thermocouple at which the electromotive force of the thermocouple attains its maximum value, when the cold junction is maintained at a constant temperature of 0°C.
So, answer is yes.
