Due to their effective shockproof system these Dial Gauges have an exceptionally long service life. A gear rack sleeve covering the length of the spindle is arranged and sprung in such a way that shocks against the measuring insert are not transferred to the movement. The Dial Gauges are robust in operation.
Their precision is maintained with practically no limitations.
Our models M 3 T and M 3 a T have exactly the same technical data, but are not shockproof.
Spindle and stem are made of resistant stainless steel. The spindle is lapped.
