The use of the bimetallic thermometer

Methods before a 1, measurement and observations of the bimetallic thermometer is used, understand its range ( Measuring range), And dividing value ( Each small case the corresponding temperature value) ； 2, make the sheath maerial of the thermometer measurement with good contact with the liquid to be tested, To be submerged in the liquid being measured) ； 3, to stay stable readings after reading; 4, when reading the thermometer sheath maerial to stay in the liquid to be tested, can't take readings. Method 2 1 before measurement to estimate the temperature of the measured liquid; 2 according to estimate the temperature of the range of suitable bimetallic thermometer. 3 the sheath maerial of the thermometer should be completely submerged in the liquid under test, but don't run into the bottom of the container and the container wall. 4 sheath maerial completely submerged in the liquid under test to wait for a while. Such as its stable readings before reading. 5 readings, sheath maerial want to remain in the liquid is measured. 6 the line of sight to the liquid column in the table above physiognomy thermometer. Measurement results are correctly recorded Numbers and units.
