You then don't understand the system operation. The probe is the hot
junction of dis-similar metals. Your meter whether it is electronic or analog
still is the cold junction. There is no outside power. Your meter display maybe
very accurate but it can't make the data any better than what the closed loop
provides.

Sorry Cy, most of us use modern sensors, analog to digital converters and
digital displays. Modern systems are very accurate.
