Helium mass spectrometer

              Helium mass spectrometry leak detection technology is an indispensable technology in the field of vacuum leak detection, which has been widely used in resistance furnace leak detection. Helium mass spectrometer leak detector is an air tightness detector made of helium as leakage gas according to the principle of mass spectrometry. It is composed of ion source, analyzer, collector, mass spectrometry chamber composed of cold cathode ionization gauge, air extraction system and electrical part.
