When it comes to monitoring ozone levels in sensitive environments, precision and reliability are non-negotiable. The Model 465L UV Photometric Ozone Monitor stands out as an exceptional instrument for low-level ozone safety and process applications, delivering robust performance, advanced diagnostics, and industry-leading accuracy.
Designed for environments where even trace levels of ozone must be closely monitored—such as laboratories, semiconductor facilities, and cleanrooms—the 465L offers cutting-edge features backed by NIST-traceable calibration and sophisticated pressure and temperature compensation.
Reliable Performance, Unmatched Accuracy
The Model 465L uses the UV absorption method based on the Beer-Lambert Law, a highly stable and accurate technique for measuring ozone. With a lower detectable limit (LDL) of just 3 ppb, it is ideal for applications that demand ultra-low detection capabilities.
Standard temperature and pressure compensation ensure that your measurements remain accurate regardless of ambient conditions. The instrument also boasts minimal zero drift (as low as 0.005 ppm/month), ensuring consistent long-term operation with reduced need for recalibration.
Flexible Configuration Options
The 465L is available in two enclosure styles:
- 19″ Rack Mount for clean, space-efficient installation in control rooms
- NEMA 4X Wall Mount for harsh or outdoor environments
It can be configured as a single-stream unit or upgraded to a multi-stream system monitoring up to six individual sample lines, making it scalable for large facilities or multi-zone safety applications.
User-Friendly Interface and Remote Access
With menu-driven software, operators can easily configure and calibrate the device in the field. The 465L’s graphical display shows real-time test values and system warnings, while built-in diagnostics continuously monitor performance and provide alerts if conditions fall outside safe operating ranges.
Every front-panel function is also accessible remotely via the RS-232 port, and optional Ethernet connectivity enables integration into modern digital monitoring systems.
