A. Product introduction
WSS series bimetallic thermometer is a kind of measurement in the field of low temperature test instrument.Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature.
The main features
The scene display temperature, intuitive and convenient;Safe and reliable, long life;
Many kinds of structure forms, can meet different requirements.
2. Working principle
Bimetallic thermometer is based on the ring around the made of bent bimetallic strip.End is heated expands, turns the pointer, the instrument will show should value.
