Touch screen display unit for 1 air gage

Multifunctionnal display unit for 1 air gauge




    The M1 display is a revolution in the field of air gauging.

    This is the last generation tool for dimensional control with an air gage : air ring, air plug gage, air fork etc.


    Forget the old analogue displays and columns with complicated setup or lack of communication possibilities : The M1 is compatible with all the air gage brands available making possible to keep your actual air gage and to use this modern and versatile display.


    Thanks to is user friendly interface and its general simplicity the M1 is a device that will be immediately adopted by every operator.


    The M1 has several means of communication, USB and RS232 (ASCII or MODBUS RTU) to remote control the device and/or send the measurements to an external system. It is also possible to plug a USB stick for data export on a CSV file. It is compatible with several SPC softwares like Q-DAS® /qs-STAT®



    The M1 display is adapted for both manual inspection with an operator or automatic control on a machine, thanks to its optional Inputs/Outputs module or the modbus RTU protocol for PLC communication.




    Its housing machined in a solid aluminium block offers to the M1 an incomparable robustness even when use in the most severe industrial environments. The 4''3 resistive touch screen display can be used with gloves.

  • Metric (µm or mm) or imperial measurements (inches)
  • Different languages installed (including Japanese, Chinese, Korean). New language can be installed upon request
  • Data export on a USB stick (.csv file)


USB Connection


The M1 is fitted with a mini-USB connector with 2 functions :

1. Power supply through a wall mounted transformer. This transformer supplies a regulated 5V/1A DC voltage.
2. Measurement transmission. If you connect your M1 to a PC, the PC will detect and install automatically the M1 as a standard USB keyboard with the standard drivers of your operating system (Windows, Mac OS etc..). When you will send the measurement, the value will be writting on your PC screen where your cursor is, in the same way as it would have been typed with a keyboard.
No need to install any specific driver or software.





The RS232 interface allows to monitor and configure all the M1's functions through ASCII commands or MODBUS-RTU protocol.
The M1 is compatible with several SPC softwares, like Q-DAS® /qs-STAT®



The M1 is very easy to configure and to use thank to its user friendly interface :

Display with needle indicator, control limits and classe indication

1 characteristic display with control limits (Warnings)

Icon desktop (Configuration menu)

Configuration window

Display mode without tolerances and direct access to preset modification





As an option, it is possible to connect up to 4 M-Bus I/O module fitted with 8 optocoupled inputs/outputs. (= max 32 I/O)

Available functions :
- Go/NoGo
- Calibration/Preset
- Start dynamic measurement
- Measurement transfert
- Zero
- Stop
- etc..

A useful screen allows to assign a function to a pin of the module very easily. 8 virtual Buttons/lamps allows to easily test your wiring.
