SFJ-231 Vaccum Pump Helium Leak Detector Device With Sniffer and Spray Gun
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.
