The Model 480L 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 under all conditions.
The Model 480L is housed in a splashproof NEMA 4X wall mount enclosure and can be purchased either as a single stream unit or as a multi-channel unit capable of monitoring up to six individual sample streams. The Model 480L has been designed to deliver excellent performance, high reliability and simple operation. The modular design allows for easier field serviceability. Operating parameters can be easily set up in the field using the operator-friendly menu driven software.
The mercury-free UV LED source in the detection cell makes this process ozone monitor the first of its kind.
Built-in diagnostics provide warning signals in case operating parameters are out of range. Test values can be viewed while the Model 480L is operating. These displays, warnings, and self-diagnostics, along with the modular design, allow maximum uptime. A self-adjusting pump allows for longer pump life. In addition, improved communication interfaces allow for greater productivity. Any function that can be set or monitored from the front panel can be remotely set or viewed.
