An indicating thermometer can be roughly classified into the liquid filled type, in which a principle that charged liquid expands and contracts according to temperature change is applied, and the gas filled type, in which a principle that charged inert gas pressure changes according to temperature change is applied. Additionally, in the liquid filled type, two types, the mercury filled type and the liquid filled type, exist. This catalog is formed by classifying these thermometers into a thermometer with mercury and that without mercury.
