Volumetric Flow Tester – TEX-G4-VZ


For a repetitive and ultra-stable leak test the G4-VZ model is the one to use.

Having Swiss technology for mass flow measurement, it is perfect for applications where speed and repeatability are essential.

It is featured with a precision electronic regulator, digital electronic meters, a flow sensor, and an air filter. Its main application is measurements of air escapes from 0,1 to 200NL/min.

It uses prAIR-SURE technology, which keeps pressure stabilized at the nominal value dynamically during the measurement process, thus guaranteeing reliability and high repeatability of the results.


  • 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
  • Auto-cleaning and dynamic auto-test
  • Warranted digital calibration with a built-in certificate and validity electronic control
  • Ethernet communication interface(Modbus and HTTP) and 2 RS-232 ports (Scanners and printers)
  • USB Flash Disk inlet for the collection of results, backup, and updating, among others
  • Picture of the registered product on the equipment
  • Statistic graphs of the results available on the screen
  • Ultra-fast 24-bit A/D converter
  • Simple and intuitive interface
  • Compatible with imported devices and with TEX-G3 line
  • Validated according to the European Community (CE Seal) for emissions and electromagnetic interferences
  • Register of up to 1,000 tested parts with up to 16 inputs for each part
  • Events schedules for reminding the operator about necessary actions to be performed throughout the day/shift
  • Languages: Portuguese, English, Spanish or other language (on demand)
