  • SF6 Gas Detection For HV GIS Switchgear - Crowcon F-Gas Detector

    Sep 30, 2020 · Gas leakage can also mean a substantial economic cost to the industry, since F-gases are very costly chemicals to replace. The Crowcon F-Gas Detector utilises a high quality infrared (IR) sensor specifically calibrated to detect the F-gases commonly in use. The tri-coloured LEDs that indicate the operating status make it is easy to operate.
