Bimetal Thermometers
Bimetal thermometers are reliable and accurate mechanical temperature measuring instruments based on the principle of thermal expansion of bimetallic strips. They operate without electricity or wiring, making them suitable for on-site temperature indication in a wide range of industrial applications. Back-connect models are commonly used for eye-level reading in process systems. The instruments can be recalibrated using an adjustment screw on the back of the dial. These thermometers are available in multiple configurations to meet different requirements.
