gis sf6 compressor alternatives for sustainability and safetyFurthermore, as SF6 is a potent greenhouse gas, it must not escape into the atmosphere. An SF6 gas density monitor warns operators of dropping levels that indicate contamination and/or leaks. WIKA's SF6 gas density monitors are temperature compensated and hermetically sealed to shield measurements from atmospheric pressure fluctuations and differences in mounting level.

suppliers calculator for sustainability and safetyWhen insulating switchgear or transformers, sulfur hexafluoride (SF6) is used. Since it is technically almost impossible to hermetically seal these systems, emissions can escape into the environment. Gas detection systems from Dr ger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.Location: Riyadh 11393
