NDIR SENSORS FOR sf 6 MEASUREMENT - smartGAS

insulating gas (sulphur hexafluoride) is a non-com- bustible and non-toxic gas. Throughout the world it is used primarily for insulating electrical high-voltage switching systems, transformers and cables. It is also used as an etching gas in semiconductor produc- tion and as a tracer gas in environmental simulations. The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute Sulfr hexafluoride quantities in indoor air.Get price
