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.
