Measured melting point range, initial melting and full melting temperature should add correction value △ t
The correction value △ t is calculated according to formula (2):
△ t =0.
In the formula: t 1 -the measured initial melting temperature or full melting temperature, ℃;
t 2 —The temperature of the auxiliary thermometer, ℃;
h—The height of the exposed part of the mercury column of the thermometer, measured in degrees
