  • SF6 Transmitter - Draeger

    Increased safety, cost reduction and climate protection. When 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 Dräger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.
