AQMS-550 is equipped with an internally mounted catalytic converter set at 315°C to convert H₂S to SO₂. Bypassing the sample through an SO₂ scrubber which removes any SO₂, the H₂S is converted to SO₂ using this internal H₂S converter and measured using the pulsed fluorescence technique. AQMS-550 H₂S analyzer adopts UV fluorescence principle with an internal thermal catalytic converter to measure H₂S in ambient air at levels commonly required.
