Our dial thermometers work on the bimetal, expansion or gas actuation principle.

Diverse connection designs, stem diameters and individual stem lengths enable a flexible measuring point design. Dial thermometers with capillaries are particularly versatile. All thermometers are suited for operation in a thermowell if necessary.

Gas-actuated thermometers fall within the scope of the 2014/68/EU directive (previously PED 97/23/EC), without additional adapted thermowell as “pressure accessories” and also in the non-fitted state or fitted within a thermowell as &l ... More
