sf6 emissions leak testing Schneider

Sulfur hexafluoride (sf6-gas) 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 sulfur atom.
