Product Overview

The API-465H is a microprocessor based high concentration ozone monitor that measures ozone in process gas streams such as water treatment, food processing, and research applications. This monitor has been designed to give accurate and stable readings over long periods of time with little or no maintenance. The wall-mount version is in a NEMA enclosure and is extremely hardy. The rack-mount version is a good choice for including in systems.  Review the manual here.
