buy sulfur hexafluoride probe GAUGE
Sulfur hexafluoride (SF 6) is inert (won't mix with anything) and non toxic.It can do some surprising things even in small quantities. Except, don't try these at home for two reasons: (1) you have to be trained in its correct use and handling and, (2) SF 6 is quite expensive.

Asia insulating gas Low pressure Prospect
Without increasing the filling pressure or adding solid insulation, AirPlus is available in the same compact switchgear dimensions as the already established ZX2. Due to switching inside vacuum bottles, also with AirPlus the gas properties are constant over the complete switchgear lifetime, which makes the medium voltage gas compartments maintenance free.

Asia sf6 Gas tank Dangerous
2021/8/27A recent study suggests that the UK's use of SF6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of SF6 to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.
