Helium Vacuum Mass Spectrometer Leak Detector with Sniffer
Introduction of Helium Leak Detector
Helium mass spectrometer leak detector is an instrument for rapid
positioning and quantitative measurement of leakage of sealed
containers. 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. In addition, the helium mass
spectrometer leak detector selects non-toxic, non-destructive and
light inert gas helium as the search gas, so it is safe and
reliable.
