450i is the H₂S/SO₂ analyzer of the iSeries family. Hydrogen sulfide is converted to SO₂ in a heated converter; SO₂ is then measured by the pulsed UV fluorescence method. When a selective SO₂ scrubber is used, H₂S alone can be monitored.
Refineries, petrochemical and gas processing plants, wastewater treatment and environmental monitoring stations are typical areas of use.
450i features
- H₂S and SO₂ measurement on one instrument
- Internal zero/span assembly and permeation oven options
- External converter and selective SO₂ scrubber configurations
- Bench or rack mounting
