Get PriceSulphur hexafluoride is an inorganic, colourless, odourless, non-flammable gas which is an excellent electrical insulator. It is an extremely potent greenhouse gas therefore it is important to minimise leaks of it to the environment. It absorbs strongly in the infrared, so NDIR sensors are ideally suited to detecting it at low ppm concentrations.People also askIs sulfur reactive?Is sulfur reactive?Sulfur is very reactive and will combine directly with many elements. It will equilibrate with hydrogen to form hydrogen sulfide at elevated temperatures and will burn in oxygen and fluorine to form sulfur dioxide and sulfur hexafluoride.Sulfur Hexafluoride - an overview | ScienceDirect Topics
