Brochure leak rate for proper equipment

Once the proper test vacuum has been achieved, the tester is zeroed to get rid of background helium levels. Then helium is sprayed around the VUT. If there is a detectable leak, the mass spectrometer quickly starts to see an increase of helium. The number of helium ions counted by the mass spec is expressed as a leak rate of the VUT.
