M4 and M4Star are ideal solutions for outer diameter measurement, with mechanical measurements using indicators and electronic measurements using hard wired or wireless transmission systems. A system that uses custom measurement depth can be used to measure the diameter near the shoulder. The measuring instrument consisting of a ring body and a sturdy rotating disk is designed to maintain their technical performance even under harsh operating conditions.

M3Star and QuickSnap are manual calipers designed to measure the outer diameter between shoulders on crankshafts, camshafts, and similar components. These models of measuring instruments have simple tool replacement, so the same equipment can be used to measure different diameters, and indicators, hard wired, and wireless versions of the measuring instruments can be obtained.

M1Star OD is an outer diameter measurement solution designed to be compatible with accessories within the M1Star range.
