Model 450H
Single Channel Process Ozone Analyzer
The Model 450H UV Photometric Ozone Monitor is an extremely stable
analyzer, ideal for monitoring process ozone in water treatment plants,
critical semiconductor processes and other applications that require
long term stability and high accuracy.
The Model 450 has been designed for ease of use and to deliver
excellent accuracy, stability and reliability. It is available in
19”
rack mount and NEMA 4X wall mount enclosures.
Operating parameters such as process alarm settings and units of
measurement can be easily set up in the field using the
operator-friendly, menu driven
software. Built-in diagnostics provide visual and audible warning
signals if operating values deviate beyond acceptable limits,
predicting possible future malfunctions.
Test values can be viewed while the Model 450H is operating. These
displays, warnings, and self-diagnostics, along with plug-in cards,
allow the Model 450H
to be quickly repaired. In addition, any function that can be set or
monitored from the front panel keyboard display can be remotely set or
viewed through the bi-directional RS-232 port. Factory calibration is
per the International Ozone Association’s KI procedure.
