1 Bimetallic Thermometer ~ Application It is one kind of t hermometers to measure middle and low temperature on the spot. It could be used to directly measure temperature of liquid, vapor and gas ranging from -0 to Features 1.directly display temperature on the spot 2.high reliability and long life expectancy 3.many structure forms to meet different demands Operation Theory Bimetallic thermometer is based on bimetal bended into ring shape. One side of bimetal expands in time of being heated, which results in revolving of indicator, then the meter will indicates the corresponding temperature value. 1. JB/T ,, 3. (1.0), s 5.
