Overview

The OT-4XX combines oxygen sensing with an integrated display, allowing operators to view measured oxygen levels directly at the installation point. It continuously detects oxygen concentration and translates the reading into standard signals for monitoring and automation systems. A replaceable sensor simplifies maintenance, while wall- or duct-mounted configurations provide installation flexibility. With a practical enclosure and straightforward mounting, the transmitter offers a convenient approach to continuous oxygen-level supervision in monitored environments.
