sf6 Gas Mixture concentration industry

The model GA25 analysis instrument is a cost-effective solution for determining the concentration of SO 2 in sf6 gas-filled equipment. The concentration of SO 2 is an indicator for the presence of decomposition products in sf6-gas gas.. Easy to use The advantage of the GA25 over conventional single-use test-tubes lies in the reproducibility of the measured value and the simple operation.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 20203. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
