Compared with bubble identification method, pressure decay method and halogen leak detection method, the helium mass spectrometer leak detection method has high detection sensitivity, high speed and wide application range.It can realizes fast and accurate detection of helium or hydrogen through vacuum helium injection, suction lance, helium hood, back pressure, and other detection methods for a variety of demanding and harsh industrial applications.
