The Model 465M is a microprocessor based medium range ozone monitor for measuring process ozone concentrations in water treatment, food processing, and research applications. The design has been specifically optimized for applications requiring the measurement of ozone at near-ambient pressure such as water treatment contactor off-gas measurement. The Model 465M has been designed to give accurate and stable readings over long time periods with little or no maintenance or calibration. The Model 465M is available in a NEMA 4X wall mount enclosure.

• UV Absorption (Beer-Lambert Law) measurement with dual detectors that compensate for UV lamp intensity changes
• Microprocessor controlled with menu-driven software and ranges from 0-1000 ppm to 0-10,000 ppm
• Built-in diagnostics and self-check warning alarms for maximum uptime
• Standard temperature and pressure compensation for accurate, stable long-term readings
• Optimized for near-ambient pressure sampling with optional Sample Conditioning System for humid environments (NEMA 4X only)
• Bi-directional RS-232 (MODBUS RTU) port with optional Ethernet (MODBUS TCP/IP) for remote operation
