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
changes 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 liquid filled type, exist. This catalogue is formed by
classifying these thermometers into a thermometer with
mercury and that without mercury.
• These thermometers are classified into the liquid filled
type and the mercury filled type according to a
temperature sensing method, and into the remote
type and the direct type according to the function.
• The wide variation complying with extensive environments
and applications is provided.
