Helium leak testing unit

Unit for quick and precise leak testing of vacuum tight series components and helium recovery

Special features

  • Filling of the test object with helium inside the chamber (integrated gas handling)
  • Built-in calibration reference leak
  • Evacuation of the chamber
  • Test time approx. 5 minutes
  • Integrated helium recovery
  • Manual sliding door with pneumatically controlled door lock
  • Automatic control and colour touch panel with PC connection

Technical data
