The Model 480M is a state-of-the-art medium range ozone monitor. 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 480M provides accurate and stable readings over long time periods and was designed with the user in mind. The modular design allows for easier field serviceability. The Model 480M is housed in a splash-proof NEMA 4X wall mount enclosure.
The sensor module contained in the Model 480M 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 source intensity.
The mercury-free UV LED source in the detection cell makes this process ozone monitor the first of its kind. A self-adjusting pump allows for longer pump life. Improved communication interfaces allow for greater productivity.
Built-in diagnostics provide warning signals in case operating parameters are out of range. Test values can be viewed while the Model 480M 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.
