  • SF6 Gas Analysis

    SF6 is an extremely stable, non-flammable and highly electronegative gas with excellent dielectric properties. It is commonly used in medium and high-voltage electrical equipment as an electrical insulator, arc-quenching and cooling medium. However, SF6 is classified as a greenhouse gas and must be kept within a closed circuit
