Bimetal Thermometer-Model No. TB4_

Bimetal thermometers use two metals with different　temperature expansion coefficients wound in a helical shape and indicate the temperature by transmitting the deflection of the metal by temperature change to a pointer.

• Error due to ambient temperature is smaller than that of the filled type.
• Since there is no filled liquid, it is safe. (No pollution)
• Simple design and reasonable price.
