The M3 is the last generation tool for dimensional control from 1 or 2 air gauges, probes or scales. This version (13020, 13000) allows you to connect : Incremental probes (Heidenhain (example Heidenhain MT101), Magnescale DK with an adaptor and Mitutoyo LG with an adaptor). Linear scales (Heidenhain, Magnescale), Rotary encoders.

Key features

2 measurement configurations (2 characteristics)
Different display modes with 1 or 2 measurements, with or without tolerances.
Tolerance limits and control limits (Warnings).
Absolute or relative measurement
Direct or dynamic measurement (Min, Max, Max-Min , Average, Median)
USB communication “virtual keyboard”
Modbus-RTU or ASCII Communication on RS232
Sorting by classes of size, up to 16 classes by characteristic
Possibility to connect an optionnal I/O module with 8 optocoupled I/O.
Possibility to connect a multi-function footswitch (measurement transfert, calibration etc…)
Optional external module for temperature compensation from PT100 sensor or Type K thermocouple.
Easy to use and reliable

Thanks to its user friendly interface and its general simplicity the M3 is a device that will be immediately adopted by every operator.

The 4”3 resistive touch screen display can be used with gloves.

This digital readout has several way of communication, USB and RS232 to remote control the device and/or send the measurements to an external system.

Its housing machined in a solid aluminium block offers the M3 an incomparable robustness even when used in the most severe industrial environments.

User friendly interface

Connect to Magnescale probes

Improve your inspection process

Graphical interface

Measurements can be displayed with different types of barographs and needle indicators for ease of use.

USB connection

The mini-USB provides power to the M3 and allows for measurement transmission

Many functions and measurement mode can be selected through the keyboard:

Tolerance limits, Control limits (warnings) Dimension of the master piece (reference piece)
Calculation formula (C1, C2, -C1, -C2, C1+C2, C1-C2, -C1+C2, -C1-C2, 3 points diameter)
Calibration
Different display modes with 1 or 2 characteristics displayed
Direct or dynamic measurement (Max, Min, Max-Min, Average, Median)
Absolute or relative measurement
Sorting by classes of size, up to 16 classes by characteristic
Measurement direction inversion
Possibility to lock selected functions with a password
Display resolution (from 2 to 5 decimals)
M-Bus connector for the optionnal connection of a module with 8 input/outputs (go, nogo, preset, send measurement etc…)
Metric (µm or mm) or imperial measurements (inches)
Selection between 2 measurement configurations (2 characteristics)
Automatic change of program by moving the probe
