What do Thermometer Testers do?

Heats and cools thermometers to test flow of mercury, remove excess mercury, and establish calibration reference points: Places thermometer alternately into hot water and crushed ice and rubs thermometer across corrugated pad to force excess mercury and mercury vapor from thermometer into temporary top chamber of thermometer. Spins thermometer in centrifuge to force remaining mercury back into bulb at bottom of thermometer. Observes rise and fall of mercury column and rejects thermometer if particles of mercury or dirt cling to bore, or bore constrictions prevent specified rise and fall of mercury. Heats thermometer at two known temperatures and marks height of mercury column on tube as reference points for calibration.
