Grafx MF – Mass Flow Leak/Flow Tester

The ATEQ GraFX MF is a touch screen air/air leak detector used to test the air-tightness of parts on production lines.



GraFX Touch Screen
Part of the Grafx simplicity comes from using a touch screen. What ATEQ® had in mind was first and foremost an easy interface that could be understood by even beginners in the leak detection field. Moving forward, it was obvious that combining an easy interface with a touch screen would transform the flow meters product line, and the Grafx MF – Mass Flow Leak/Flow Tester into a plug and play machine.



The ATEQ® Grafx easy enough for anyone to use:

  • A production engineer will find it very easy to set up and remember.
  • A user will find it clear to read.
  • A quality control engineer will get the data they are expecting in no time.
  • Any training around the Grafx will show how easy it is to teach leak detection to new comers … thanks to the interface.


GraFX backward compatibility

One of the most important features is the ability of the leak tester to plug into existing PLC’s and test benches without having to reprogram everything. ATEQ®’s Grafx I/O is compatible with ATEQ®’s previous generations leak testers and flow meters. In addition, the Grafx features more modern interfacing (Ethernet and USB), so customers can be sure that it is also fully “Forwards compatible”.


Many of ATEQ®’s leak testers and flow meters are being installed into quality labs or they are simply being set up in labs prior to being installed on the production line. These test conditions require a small unit with a fast and clear interface and gigantic memory to store all the trial parameters and tests.

ATEQ®’s Grafx has it all.

flow metersMass Flow Meters

The Mass Flow technology converts a mass of air going through a laminar flow element into a leak value. Should the test part leak, a flow will take place between a reference part and this leak, forcing the air to go through the Mass Flow measuring device that will convert it into a leak value such as cm3.atm/h.

However, unlike traditional Mass Flows, our technology can handle “large leaking” parts on the line without having to reset the unit. And unlike our competitors again, we do not use heating elements to measure the mass of air, thus reducing the sensitivity to contamination.

We’ve also put our expertise in high pressure testing into the pneumatics of this unit, allowing it to measure with a high level of accuracy at test pressures of up to 20 Bar (300 PSI).

Finally, our Mass-Flow technology comes with the latest temperature compensation feature making sure you get the best results in the industry in the toughest conditions.

Leak Ranges (in cm3.atm/min):

2 or 20 or 200 cm3.atm/min

Maximum test pressure:

20 Bar

Pressure measurement:

1% of the pressure + 2 digits and 0.1% of full scale resolution
