Deploying a permanently mounted oxygen deficiency monitor in areas where inert gases are stored or piped is highly recommended. Like most things in life, not all oxygen deficiency monitors are the same. Alpha Omega Instruments Series 1300 Oxygen Deficiency Monitor has an array of features and safeguards that makes it today’s premier monitor.

The Series 1300 is a digitally-controlled instrument with a measuring range of 0-30%. Oxygen values are displayed to the nearest tenth of a percent on a high contrast front panel liquid crystal display (LCD).   The monitor is housed in a resilient polycarbonate, wall mountable general purpose enclosure. Standard input power to the Series 1300 is 90-264 VAC, 47-63 Hz. and 18-36 VDC powered systems are available. The eloquence of the Series 1300 is its simple operation, as well as its ease of expandability. Included are four individually adjustable Form C alarm relays, each rated at 10 amps (250 VAC). The Series 1300  can be programmed to provide a maximum of nine individual alarm events. Two scalable analog outputs (4-20 mADC and 0-20 mADC) are standard, as is RS-232 serial communications. Each Series 1300 includes an internally mounted audible alarm rated at 85 decibels (nominal) as well as visual alarm indicators. The Series 1300 can control up to a maximum of 8 remote optional horn and strobe alarms.


Full Three Year Sensor Warranty Sensor
Unprecedented sensor warranty for trouble-free and cost-effective operation.
Multiple Sensor Operation
Per point pricing under $1K (with 3 sensors)
Four Alarm Relays Standard
Users can select a multiple of alarming functions.
Insensitive to Air Currents
Won’t produce erroneous oxygen readings from air movement as does high temperature zirconium oxide sensors
Protects from Frequent False Alarms
Helps to alleviate false low oxygen alarms typical of fuel cell oxygen sensors.
No sensor failures from high temperature fatigue.
When heated zirconium oxide sensors fail, often both the sensor and electronics board needs replacement-a costly proposition.
Built-in Data Logger Standard
Provides easy method of downloading and displaying oxygen values
Open sensor diffuser
Does not require a pump for aspiration of the air.

Installation Configurations



The Series 1300 can be equipped with a local oxygen sensor and/or up to two remote sensors. The sensors  featured in the Series 1300  are extended life electrochemical oxygen sensors designed with a proprietary Enhanced Electrolyte System (EESTM) that extends the life expectancy of the sensor to years instead of approximately 12 months typical of most “fuel cell type” sensors.  The oxygen sensors in the Series 1300 are designed with open diffusers eliminating the need to use sample pumps. Alpha Omega Instruments backs each Series 1300 oxygen sensor with a full three-year warranty. Users can expect sensor life well beyond 5 years, helping to ensure reliable and trouble free performance.
