Model 450
Single / Multi-Channel Ozone Analyzer
The Model 450 UV Photometric Ozone Monitor is an extremely stable
analyzer, ideal for critical low-level ppm safety and process
applications. Its calibration
is NIST traceable and the included pressure and temperature
compensation ensure high accuracy under all conditions.
The Model 450 is available either as a single stream unit or as a
multi-channel unit capable of monitoring up to six individual sample
streams. The Model 450
has been designed to deliver excellent performance, high reliability
and simple operation. Operating parameters can be easily set up in the
field using the operator-friendly, menu driven software.
Built-in diagnostics provide warning signals if the analyzer
malfunctions. Test values can be viewed while the Model 450 is
operating. These displays, warnings, and self-diagnostics, along with
plugin cards, allow the Model 450 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.
