SF 6 gas density monitors: reliable warning against low gas quantities . Sulfur hexafluoride (SF 6) is an extremely effective electrical insulator for medium and high voltage switchgear.For proper insulation, gas density must remain within certain levels. Furthermore, as SF 6 is a potent greenhouse gas, it must not escape into the atmosphere. An SF 6 gas density monitor warns operators of

2017/8/243. 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.
