WIKA dial thermometers work on the bimetal, expansion or gas actuation principle. This enables scale ranges of -200 … +700 °C (-328 … 1,292 °F) in different class accuracies, response times and resilience to environmental influences. 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.
