  • NDIR SENSORS FOR SF6 MEASUREMENT - smartGAS Mikrosensorik

    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. Its global warming potential (GWP) is almost 24,000 times higher than that of CO2.
