  • SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS

    The high sensitivity and very small lower detection limit enable the 50 ppm sensor to detect even minimal sulphur hexafluoride leaks with absolute reliability. Another typical application for the highly sensitive FLOW EVO SF 6 sensor (50 ppm) is detection of SF 6 in environmental simulations. Since sulphur hexafluoride is not present in the atmosphere and non-flammable and non-toxic, it is used in very small concentrations as a tracer gas for real-time analyses of the spreading of fire gases
