Micro-flow Leak Tester – TEX-G4-VE


For air-tightness measurement of leak units and in order to getting results traced by calibrated certificates, use the G4-VE model. This product has Swiss micro-leak technology, and it is featured with dedicated pneumatics.
The G4-VE model is fed with pressured dry air. After filling a tested part with air, it waits until it stabilizes, and then measures the remaining flow by means of a mass micro-leak sensor, by directly indicating the volumetric leak of the tested part. Then the leak is compared with the set parameters, and then the tester accepts the part should the part be in compliance.
It has electronic pressure setting, which makes this tester the ideal device for tests to complex volumes where the differential check cannot stabilize properly due to thermal variations in the part as well as in the environment.
In cases related to reference parts that are difficult to be implemented, the derived model G4-VF can be applied with both internal reference volume and automatic test start. The product is also featured with continuous measurement mode for further assessment of the leaking points.
