High Precision SF6 Gas Leak Detector - Huatian Electric Power principle of sulfur hexafluoride leak detector is as follows: when the concentration of sulfur hexafluoride gas contained in the air changes, the degree of ionization of the mixed gas under the action of high-frequency electromagnetic field will also be different, and the concentration of sulfur hexafluoride can be reflected by detecting the ionization degree.
