Manual Snap Gauge


M2, the Marposs line of electronic manual gauges for shafts, provides the automotive market with essential products, suitable for different measurements of outside diameters on the shop floor.

Through the elaboration of single and multiple sections, the gauges allow to perform fast and extremely precise inspection.

The mechanical structure, solid and maneuverable, is designed for continuous manual measurements: it guarantees ease in handling and high reliability over time.

  • Extremely precise measurements to assure best quality controls
  • Maneuverable to perform fast and continuous inspections
  • Rugged to maintain high reliability over time
  • Complete solution for checking all smooth outside diameters of crankshaft

M2 is designed to measure crankshaft diameters, particularly the main and pin bearings through the inspection of 1, 2 or 3 sections.

The electronic manual gauge, designed according to customer specifications, provides different checks of:

  • diameters, in a range from 18 to 120 mm
  • ovality
  • barrel-shape
  • taper

Special snap gauges can be designed upon request, in order to measure different kind of shafts or any other outside diameters, offering a complete solution for customer parts.

Due to the excellent maneuverability and high hardness, M2 is suitable for fast, continuous and extremely precise inspection.

Each snap gauge can be put away easily by a hook placed in the handle, so its integration in a production line is effortless.

The interchangeability of wearable details assures a quick maintenance of the product.

The connection of the manual gauge to gage computer is accomplished by extension cables or wave.

M2 snap gauges are supplied in short time thanks to an efficient production process.
