The International Bureau of Weights and Measures (BIPM) defines it as “the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology”, it is the science that fixes the accuracy of definite measurement situations.

Special laboratories perform both metrology and calibration, there, high qualified technicians perform analysis in adjunct to calibrations to isolate the work performed from influences that might affect the work.
In industrial metrology, numerous issues beyond accuracy necessitate the usability of metrology methods, and standards include dynamic control plans, also known as “dimensional control plans”, or “DCPs”.

Particularly suitable to perform measurements close to a shoulder, it can be used both directly on the workpiece and as a simple fixture using the optional support.

It is composed of a ring body and standard interchangeable nosepiece; within its range of use each ring is completely retoolable by changing the nosepiece and the contacts.

Accurate, rugged and reliable, needs no maintenance and has practically no operating costs.

Thanks to its outstanding qualities, it can be used in the most difficult working conditions without any effect on its technical characteristics.

The measurement value can be displayed on the TESTAR E18, E4, E4N and, through the Gage Box‚Ñ¢ data acquisition system, on the E9066s‚Ñ¢ Industrial PC.

It is available in two versions: with separated or added signals. The last one minimizes the number of connectors (one for each pair of contacts) which permits connection to a Marposs single-channel E4 electronic amplifier. In this case, the connection between the M2 mechanics and the E4 electronics is accomplished with an extension cable.

Due to its accuracy and ease in handling, the M2 snap gauge provides the automotive market with an essential product, suitable for any type of measurement performed on main bearings and pin bearings. Designed for high-volume industrial production and requiring neither retooling nor maintenance, the M2 snap gauge fully deserves the title of non-stop gauge.

The major inspections are the following : 3 diametrical measurements, ovality, barrel-shape and taper.

It can be configured according to specific application needs, employing different transducer modules provided with 1, 2 or 4 input channels.
It can be programmed via local keypad or PC (by means of the specific E4N-PC LINK software, which also allows data collection).
