  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), 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 sulfurChemical formula: SF₆

  • SF6 gas detector, Sulfur hexafluoride - GazDetect | Gas

    As sulfur hexafluoride can absolutely not be detected without proper equipment (odorless and colorless gas), only an SF6 detector can accurately measure concentrations of this asphyxiating gas and properly monitor SF6 gas hazards. Thus it is advised to use a fixed or portable sulfur hexafluoride detection device or complete system.
