The Model 450H LTV Photometric Ozone Monitor is an extremely stable analyzer, ideal for water treatment plants as well as for applications such as monitoring the output from Ozone generators for critical semiconductor processes. Calibration is International Ozone Association KI traceable. Standard pressure and temperature compensation ensures high accuracy of the normalized reading. The Model 450H has been designed to deliver excellent performance, high reliability with ease of operation. Operating parameters such as 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 the analyzer malfunctions or test values deviate beyond their acceptable limits, predicting a possible malfunction of the analyzer. Test values can be viewed while the Model 450H is operating. These display 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 set or viewed through the bi-directional RS-232 port.
