The leak testing is performed by using a Sniffer probe. There are many signs that you can use to determine if you have a leak, or you can use gas detectors to easily track the levels. Nitrogen should not be used in a closed area if the possibility exists that the escaping nitrogen could displace the air in the confined space. You should consult the American. While the micron gauge is quite capable, testing for a leak in a vacuum is not acceptable practice over a standing pressure test as moisture is drawn into the system during the evacuation process. pressure test is required for a new pressure system before use or an existing pressure system after repair or alteration. Mass Spectrometer Leak Testing can be done by pressurizing the test part with helium or a helium/air mixture within a test chamber then surveying the surfaces using a sniffer, which sends an air sample back to the spectrometer.
