Product description:
Bimetal thermometer is used bimetal piece coiled helically as the senor part, it installed in the protect tube, one end fixed, one end connect with a thin axis, the pointer fixed in the axis end, when the temperature changes, the senor's free end will turn around, the pointer will generate angular displacement by thin axis, the temperature will indicate in dial plate.
The bimetal thermometer is suitable for measuring low or medium temperature, it can measure the temperature for liquid, gas or other fluid directly.
The specification is complete:bottom type, back type, adjustable angle type, electrical contact type, shock-resistance type, explosion-proof type
It has stable and reliable quality, can be widely applied in industry, agriculture, national defence and scientific research.
Shuanghuan participated in designing and drawing up the standard of bimetal thermometer.
The only factory to calibrate the temperature for twice.
