The leak detector is a highly sensitive magnetic mass spectrometer configured to register a sample gas (helium) flow. The leakage is determined by the flow of helium entering the test volume during vacuum tests, or flowing out of the test volume at an overpressure in it.
DESIGNED FOR
Measuring helium flows during non-destructive testing of tightness.
