  • NDIR SENSORS FOR SF6 MEASUREMENT - smartGAS

    The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute SF6 quantities in indoor air. No matter what SF6 concentration has to be measured under what conditions – smartGAS offers the suitable NDIR sensor. SF6 is the strongest greenhouse gas and therefore the most harmful to the environ-ment.
