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.
