450iQ is a pulsed fluorescence analyzer that measures hydrogen sulfide (H₂S) and sulfur dioxide (SO₂). H₂S is converted to SO₂ in a converter and the UV fluorescence of SO₂ is measured; with a selective SO₂ scrubber, H₂S alone can also be monitored continuously.
It is used around refineries, at petrochemical plants, in wastewater and biogas applications and at ambient air monitoring stations.
450iQ features
- Pulsed fluorescence measurement of H₂S and SO₂
- Internal zero/span valves and internal permeation oven option
- Continuous H₂S analysis with selective SO₂ scrubber
- Analog and digital outputs
- CE and TÜV-SÜD safety approvals
