The waterproof Precision Dial Gauge M 2 SW also has a bezel which can be rotated through 360°.
When changing the measuring insert attention has to be paid that the spacer disc between the measuring insert and the rubber bellows is put back again. Otherwise the Dial Gauge is no longer sealed against the ingress of contamination.
Spindle and stem are made of resistant stainless steel. The spindle is lapped.
