Continuous Water Quality Monitoring of H₂O₂

ATi’s Q45/84 Hydrogen Peroxide Water Quality Transmitter is designed to continuously measure the concentration of H₂O₂ in aqueous systems. Using a direct sensing polarographic probe, this monitor is mounted in a flowcell to measure H₂O₂ in a flowing water stream. A Peroxide permeable diffusion membrane isolates the sensing electrodes from the measured sample, providing long-term stability without electrode fouling problems. The measurement is selective for Peroxide and does not respond to most other chemicals in solution.

Please Note: This transmitter does not include a Battery-Operated version. For Portable Monitoring please view our PQ45 Portable Monitor & Data-Logger System.
