AQMS-550 continuous hydrogen sulfide (H₂S) monitor

AQMS-550 H₂S analyzer adopts UV fluorescence principle with an internal thermal catalytic converter to measure H₂S in ambient air at levels commonly required.

AQMS-550 is equipped with an internally mounted catalytic converter set at 315 °C to convert H₂S to SO₂. By passing the sample through a SO₂ scrubber which removes any SO₂, the H₂S is converted to SO₂ using this internal H₂S converter and measured using the pulsed fluorescence technique.
