Helium leak test systems for hydrogen valves

Reference project: 2-chamber test stand with manual loading

The hydrogen valve is manually placed in the test fixture, the chamber top is closed and a helium integral measurement is performed.

The detection system for the test gas is a mass spectrometer, which consists of an ion source, the separation system and the ion detector.

Brief description:

  • Manuel loading in 2 test chambers
  • Different types and variants of hydrogen valves can be set up
  • Limit leakage rate: 1x10-6 mbar*l/s
  • Test medium: 10% He / 90% N²
  • Test pressure 1-900 bar
