• gaz sf6 Gas Leak Detector SGLD-I-Wuhan Huaying Electric Power

    Sulfr hexafluoride Gas Leak Detector working principle is that when the concentration of sulfur hexafluoride in the air changes its degree of ionization under an electromagnetic field of high frequency varies at the same time. The concentration degree of sulfur hexafluoride can be displayed by a detection of the degree of ionization.
