  • Features

    The Air check O2 Oxygen Deficiency Monitor is a compact gas monitoring system that’s ideal for the continuous monitoring of inert gas storage areas, freezers, confined spaces, and other locations where low oxygen levels may pose a hazard to personnel. Unlike electrochemical sensor cells the Air check O2 zirconium cell provides stable oxygen readings even in areas where temperature, barometric pressure and humidity levels are changing. The PureAire Air check O2 Oxygen Deficiency Monitor is suitable for either indoor or outdoor use.

    The heart of the monitoring system is a long lasting zirconium sensor, which responds to low oxygen conditions within seconds and provides accurate measurements over a wide temperature and humidity range. The zirconium O2 sensor cell will operate continuously for 10 or more years and requires an absolute minimum of maintenance. There are no zero or span calibration pots to adjust and when compared to disposable type sensors, our long life zirconium O2 sensor can save up to $475 annually and will pay for itself in just over 3 years!

    Ideal for continuously monitoring oxygen levels in confined spaces or areas where inert gases are used, the Air check O2 Deficiency Monitor does not drift or loose sensitivity when the weather or temperature changes. The electronics are housed in a Nema 4X housing or optional EX for hazardous areas.

  • Advantages

    Connects to SCADA and PLC Controls
    The Air check O2 Oxygen Deficiency Monitor is 24 V DC powered and transmits continuous oxygen concentration levels to any system control data acquisition system, or programmable logic controller. The PureAire’s Oxygen Deficiency Monitor can also be operated remote up to 1,000 meters or 0.6 miles from centralized controllers.

    PureAire’s Oxygen Sensor Cell
    The Air check O2 Oxygen Deficiency Monitor uses an exclusive Current Limiting Zirconium Oxide Oxygen sensor that never requires a reference gas. Unlike concentration type zirconium cells that must have a reference gas, PureAire’s O2 monitor can operate in 100 % nitrogen environments. Capable of detecting 0 % up to 25% oxygen levels, the current limiting O2 sensor operates at a lower temperature than competitive concentration type cells. The average life of PureAire’s O2 sensor is over 10 years in most environments.
    The Air check O2 Oxygen Deficiency Monitor never needs calibration. The earth is a wonderful source of calibrated oxygen and under ambient levels; PureAire’s O2 monitor is continuously being challenged to 20.9 %. There are no zero or span adjustments to make; the only optional response test required is to subject the O2 system to nitrogen periodically.

    O2 Monitor System Features
    The Air check O2 Oxygen Deficiency Monitor is available in many different configurations. PureAire uses a sophisticated built-in CPU that is flexible to provide users with a low cost basic display only monitor or a full featured monitor with dual level, user selectable alarm relays. Other options available are Modbus digital communications or full Wireless radio communications.
