Introduction of Helium Leak Detector
Helium Leak Detector
Helium leak detector is based on the principle of mass spectrometry, using helium as an exploratory gas, to quickly locate and quantitatively detect the leakage of various containers that need to be sealed. Since helium is an inert gas, it is non-polluting to the atmosphere and safe to use; with its small atomic weight and low viscosity, helium is easy to penetrate through any leakage that may be present, and has high detection sensitivity, speed, and a wide range of applications.
