Industry version
The measuring principle of the thermometer is based on a bimetal coil in a stainless steel or brass protection tube. If the temperature increases or falls, it turns and has a direct effect on the indicator via an axis. Versions of the 608002 products comply with DIN EN 13190, class 1.

For temperature control
Contact dial thermometers are universally-applicable devices with actual value display for temperature measurement, control, and monitoring. The slow-action contact/magnetic snap contact closes or opens an electrical circuit depending on the movement direction at the set limit values.
