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 $0^\circ C$.
So, answer is yes.
