Mechanical Temperature Measuring Instruments

Our mechanical temperature measuring instruments comprise bimetal thermometers, gas-actuated thermometers and machine glass thermometers, and are suitable for temperature measurements in the range of -100 °C up to +650 °C.

An installation of electrical additional accessory is possible for gas-actuated thermometers.
For the ideal measuring point design, we offer customer-specific solutions with stem models and stem connections for almost all applications.
