The Model 450 UV Photometric Ozone Monitor is an extremely stable analyzer, ideal for critical low-level ppm safety and process applications. Its calibration is NIST traceable and the included pressure and temperature compensation ensure high accuracy. The Model 450 is available either as a single stream unit or as a multi-channel unit capable of monitoring up to six individual sample streams. The Model 450 has been designed to deliver excellent performance, high reliability and simple operation.

Operating parameters can be easily set up in the field using the operator-friendly menu driven software. Built-in diagnostics provide warning signals if the analyzer malfunctions. Test values can be viewed while the Model 450 is operating. These displays, warnings, and self-diagnostics, along with plug-in cards, allow the Model 450 to be quickly repaired. In addition, any function that can be set or monitored from the front panel keyboard display can be set or viewed through the bi-directional RS-232 port.
