The Model 465H is a microprocessor based high concentration ozone monitor for measuring ozone in process gas streams in water treatment, food processing, and research applications. The 465H has been designed to give accurate and stable readings over long time periods with little or no maintenance or calibration. The Model 465H is available in a NEMA 4X wall mount enclosure. The sensor module contained in the Model 465H uses detectors which have a very narrow band of spectral sensitivity, eliminating the need for UV band pass filters which are subject to deterioration by UV or humidity.

• UV Absorption Method (Beer-Lambert Law) with dual-detector design that eliminates deterioration-prone UV band pass filters
• Microprocessor controlled with menu-driven software and ranges from 0-5 to 0-25% w/w
• Built-in diagnostics with self-check warning alarms and programmable concentration alarms
• Fast response times (<30 seconds to 95%) with minimal zero drift and programmable auto-zero function
• Standard temperature and pressure compensation
• Bidirectional RS-232 (MODBUS RTU) with optional RS-485 and optional Ethernet (MODBUS TCP/IP)
