Product synopsis
The WSS series bimetallic thermometer is in one kind of survey the low temperature scene examination measuring appliance. The bimetallic thermometer may in the direct measurement each kind of production process - 80℃~+500℃ in the scope the liquid, the steam and the gas medium temperature.
Main feature
Scene demonstration temperature, direct-viewing convenient; Safe reliable, the service life is long;
Many kinds of structural styles, may satisfy the various requirement.
Principle of work
The bimetallic thermometer is based on circles makes the link bending shape the bimetal piece composition. When an end heating inflation, leads indicator revolving, works the measuring appliance then demonstrates should temperature value.
