Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

RH Systems - dp19, dew point mirror hygrometer, humidity

Typical ApplicationMeasurement PrincipleStandard VersionStandard EquipmentOther VersionsOptions and AccessoriesA typical application of this instrument is the spot measurement in sulphur hexafluoride (sf 6). Measurements are made at pressures between 10 mbar and 10 bar (1 kPa to 1 Mpa). Sample gas flow is effected by pressure difference between gas inlet and outlet, with a minimum of 10 mbar (1 kPa). If sample gas pressure is too low or the gas has to be measured in a closed circuit, an optional gas pump is available.Get price

SF 6 circuit breakers depends on the existence of adequate gas pressure. If the SF 6 pressure drops to atmospheric level, there is no way of telling whether the arc chamber contains SF 6, air or a mixture. As a result, there is no way to predict with confidence the performance of the interrupter under such conditions.Get price
