Pressure Decay Leak Tester – TEX-G4-SE


The G4-SE model is the ideal one to replace or improve the reliability of immersion tests. It also offers excellent cost-benefit ratio regarding the replacement of tests involving PLC and pressure transducer tests.

Functioning: it injects and measures the part internal pressure during a certain period of time. This variation is then compared with the set parameters, and then the device accepts or not the part automatically, by generating luminous signs on the digital outputs.

Its pneumatics is innovative, robust, and easy to fix, with valves specifically developed in order to guarantee perfect air-tightness of the test circuit.

It can be purchased in manual or automatic pressure setting versions.


  • Its fully removable pneumatic module facilitates maintenance/calibration
  • Own valves with air-tightness-oriented technology
  • Access control with NFC technology (RFID tag), with operator/user’s data registered for each test
  • 7”-color display(800 x 480px), industrially robust and sensitive to the touch
  • Pressure automatic electronic setting up to 30Bar
  • Test time auto-parameterization
