Mercury-in-Glass Thermometers for Precise Temperature Measurements Near 0°C
Abstract Experience with the calibration and field use of mercury-in-glass calorimeter thermometers provides an indication of the accuracy attainable and the necessary corrections to obtain that accuracy. Secular changes as large as 57 mK have been observed during the first three years of thermomete...
