Marposs offers a complete range of variable gauges for manual measurement, available with mechanical orelectronic measurement transducers, for high-precision control of external diameters, pins and between shoulders or close to shims on crankshafts, drive shafts etc. The Marposs range of products for external diameters represents the most advanced and reliable solution currently available on the market. M4 and M4Star are the ideal solutions for external diameter measurements, with both mechanical measurement with use of an indicator, and electronic measuring, using hard-wired or wireless transmission systems. Using the customisable measurement depth, the system may be used to measure diameters in the proximity of shoulders. The gauges, which consist of a ring body and a sturdy nosepiece, were designed to maintain their technical specifications, even under the severest operating conditions. M3Star and QuickSnap are manual snap gauges designed for measuring external diameters between shoulders on crankshafts, camshafts and similar components. These gauge models are simple to retool, so that it is possible to measure different diameters using the same device, and are available in indicator, hard-wired and wireless versions. M1Star OD is the solution for external diameter located in a recess (e.g. the external diameter of a collar located in a recess inside a transmission case). It is designed for compatibility with the M1Star range of accessories. • best metrological performance guaranteed on every gauging diameter • intuitive and easy to use; the design ensures linearity over the entire measuring range and allows zeroing with a single master
