What is your question??? If I am at a customers site and they have thermometers I try to "borrow" an oven. I put my probe beside the thermometer let it stabalize and take the reading. Then I adjust the oven to a higher temperature and check it again.

You could also use an ice bath to get 32 deg F and ambient temperature if you don't have an oven. It really depends on the range of your thermometer.

You have to determine if the LIG is a partial immersion type ( has a 76 mm line on the back that it has to be immersed to) or if it is a full immersion type (has to be immersed to the measuring point on the scale).

PUBLICATION - (NIST SP 1088) Maintenance and Validation of Liquid-in-Glass Thermometers
is a great resource.

In response to Ol Dave I do not deal with those very much. If I was you I would cut and past your response into a new topic otherwise people will not see it buried in this discussion. Good luck.
