- Product Name：Double metal thermometer
Product Introduction：
Application
Double metal thermometer is a kind of measuring instrument with low temperature and low temperature. Can directly measure the temperature of liquid vapor and gas medium in the range of -80 in -+500.
Main features
On site display temperature, intuitive and convenient
Safe and reliable, long service life;
Core type thermometer can not stop short time maintenance or replacement of the movement.
Axial, radial type, 135 degree type, universal type, complete varieties, suitable for various on-site installation need.
Working principle
The bimetallic thermometer is made of a double sheet metal film which is made of a circular ring. When heated at one end, the pointer is rotated, and the working meter shows the temperature value of the thermal electric potential.
