sulfur hexafluoride Measurement for CHINT

Sulfur hexafluoride - Wikipedia. Sulfur hexafluoride (sf6-gas) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic.
