Legacy - Oxygen Analyzer (4401)
Industrial Process Control & Monitoring
- Excellent long term stability and low drift
- Measurement inherently fails high if sensor damaged (no false zero)
- LOD = 0.5 ppm O2 gas phase
- No membranes to foul; No electrolytes to poison; No consumption of O2
- Hazardous area approvals: FM, CSA, ATEX, UL and CE
- No cross-sensitivity or damage caused by: CO2, H2S, NH3, NO2, heavy metals, ethanol, methanol or ionic species pH, S2-, SO42-, Cl-, salinity or turbidity
- Measurement independent of flow velocity
The 4401OXY analyzer optically measures oxygen in either the gas or liquid phase by utilizing quench luminescence of an oxygen specific luminophore.
The analyzer is suitable for direct field installation (NEMA 4X) in hazardous area (Class I, Division 2). The optical fiber sensor platform allows small inline sensors to be installed into sample tubing lines (1/4”), flow cells using NPT fittings, or directly into tanks or process lines using our retractable “hot tap” sensor design.
