 Description

The Model 465L 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.  An integral micro fuel cell sensor provides accurate, continuous monitoring of O2 and allows measuring of both gases in a single instrument.

The Model 465L + Ohas 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 in case operating parameters are out of range.  Test values can be viewed while the Model 465L + O2 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.
