The Model 322 Multichannel Percent Oxygen Monitoring System monitors oxygen levels at one or more locations. Typical applications include process monitoring, life support, area monitoring, controlled environments, and inert gas blanketing.

The system is designed to easily add channels for in-field upgrades, and is field programmable to meet the needs of a specific application. Oxygen probes with maintenance free sensors can be mounted up to one mile from the control unit. No zero or span gases are required. Numerous remote sensor probe configurations are available including explosion proof.
