GDWG-IV SF6 Gas Leak Detector is infrared red type leak detector (NDIR technology). It is color OLED display and real-time shows SF6 concentration. It rapidly detects SF6 breaker, GIS leakage point and yearly leakage rate qualitatively and quantitatively. It's a good device suitable for power supply department, installation and overhaul unit, power test institute.
