Hi Everyone,
Great discussion! Maybe I can add a little. When I needed a NIST
traceable certification for a thermometer, I simply ordered such a
thermometer from a large scientific supply company (the kind of company
that has a catalogue the size of a thick book). It was certified for
the
temperature that I wanted to be very accurate about. Then I used the
certified thermometer to calibrate the other thermometers in my
laboratory. My students were surprised to see the variation in
temperature readings that they got with our different thermometers!
Of course we had to warn our students that the traceably certified
thermometer was very precious, and it was not to be used for routine
temperature measurement. However even those warnings did not completely
prevent the problem of students using the thermometer as a stirring rod!
I don't know if the NIST calibrates users' thermometers, but I suspect
that they have a website and email address that can help you get an
answer.
Best wishes,
