- Leak Detector is a highly sensitive magnetic mass-spectrometer set for registration of the flow of the tracer gas (helium).
Leak is determined by the helium flow penetrating into the tested volume during the vacuum test, or by the flow of helium going from the tested volume at a excessive pressure in it.
