Whey do all types of thermocouples output 0mv at 0C? ...was that a design requirement when the T/C alloys were developed?

design
Ahhh...that whole ICE POINT reference thing ...duh thx
They don't - they output 0mv when the two parts of the thermocouple are at the same temperature. So if one end is at room temp, it will give 0 mv when the other end is as well.
This isn't anything to do with the design - it's just how the underlying physics of it works.
