465M Mid Range Process Ozone Monitor

​ ​ Note: Product contains Mercury inside​ the UV Lamps, do ​​not put in t​rash. Recycle or dispose as​ hazardo​us waste following local reg​ulations.​ ​​ ​ The Model 465M is a microprocessor based medium range ozone monitor for measuring process ozone concentrations in water treatment, food processing, and research applications. The design has been specifically optimized for applications requiring the measurement of ozone at near-ambient pressure such as water treatment contactor off-gas measurement. The Model 465M has been designed to give accurate and stable readings over long time periods with little or no maintenance or calibration. The Model 465M is available in a NEMA 4X wall mount enclosure.​ ​ The sensor module contained in the Model 465M uses detectors which have a very narrow band of spectral sensitivity, eliminating the need for UV band pass filters which are subject to deterioration by UV or humidity. Two detectors are used: one for the ozone measurement, and the other to compensate for changes in UV lamp intensity.​ Built-in diagnostics provide warning signals in case operating parameters are out of range. Test values can be viewed while the Model 465M is operating. These displays, warnings, and self-diagnostics, along with the modular design, allow maximum uptime. In addition, any function that can be set or monitored from the front panel can be remotely set or viewed through the bi-directional RS-232 port.​​ Maintenance ​​The following table provides a list of items that need regular maintenance to ensure your product remains in good working condition.
