Liquid-in-glass Thermometers

A thermometer submitted for test is examined for structural defects, errors in figuring and dividing, trapped gas or impurities, and excessive strain before calibration.

After examination, the thermometer is allowed to be stabilised in a standard condition. Calibration is usually commenced at the lowest test temperature and the chosen test points are calibrated sequentially. At each test point, readings are taken and compared with the Laboratory standards, in constant temperature baths.
