Process Ozone Monitor

The Model 460H is a microprocessor based high concentration ozone monitor for measuring ozone in process gas streams in water treatment, food processing, and research applications. The 460H has been designed to give accurate and stable readings over long time periods with little or no maintenance or calibration.

The sensor module contained in the Model 460H 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. This unique design provides a sensor which will operate for extended periods without calibration or maintenance. The flexibility of the software as well as the analog and digital I/O allow the Model 460H to interface with a broad range of devices for process control and data logging.
