The AOI Series 1300 oxygen analyzer is a digitally controlled monitor that is simple to operate and easily expandable. The monitor has a measuring range of 0-30%, and oxygen values are displayed to the nearest tenth of a percent. The monitor's extended-life, electrochemical oxygen sensors are designed with open diffusers, eliminating the need to use sample pumps for aspiration of the air. Since the monitor is insensitive to changes in ambient air flow, such as from HVAC systems, air movement will not affect readings. Deploying a permanently mounted oxygen deficiency monitor is highly recommended for areas where inert gases are stored or piped.

The Series 1300 features both front panel visual alarm indicators and an internally mounted audible alarm rated at 85 decibels (nominal). Four individually adjustable alarm relays are included, and the monitor can be programmed to provide up to nine individual alarm events. A built-in data logger provides an easy method of downloading, displaying, and storing time-stamped oxygen data.

AOI's advanced digital interface provides the ability to quickly and easily expand the capabilities of the Series 1300. The monitor includes one local sensor, but is field-expandable with up to two optional remote sensors and up to eight optional horn and strobe annunciators. The interface automatically detects the addition of sensors and/or horn and strobes, and can also detect if a sensor is enabled but not connected.
