I think this is the meter that Lewan says had a 0.5°C bias. I cannot
imagine why! That's strange. These things are highly reliable and
internally consistent.
If they are well maintained.
A thermocouple delivers only microvolts that must be amplified and
linearized.
Lewan also mentioned strange instability. If this is the same meter, it
is easily explained:
Dirty and contaminated and bended contacts. For example skin-fat can
generate electrochemical voltages on a bad contact.
