The Model 465L UV Photometric Ozone Monitor is an extremely stable analyzer designed for critical low-level ppm safety and process applications. With NIST-traceable calibration and built-in pressure and temperature compensation, the 465L ensures high accuracy in all operating conditions.
Flexible Configurations
The 465L is available in multiple designs to meet the needs of diverse applications:
- 19” rack mount or NEMA 4X wall mount enclosure
- Single stream unit for straightforward monitoring
- Multi-channel unit capable of monitoring up to six individual sample streams
This flexibility makes the 465L a reliable choice for both laboratory and industrial environments.
Performance and Reliability
The 465L delivers excellent stability, high reliability, and simple operation. Its operator-friendly, menu-driven software allows quick setup and configuration directly in the field.
Built-in diagnostics continuously monitor performance and provide warning signals when operating parameters are out of range. Test values can be viewed in real time, and modular design ensures maximum uptime.
For added convenience, any function that can be set or viewed from the front panel can also be accessed remotely through the bidirectional RS-232 port.
