  • Features

    The PureAire Dual O2/CO2 Monitor is a compact gas monitoring system that’s ideal for the continuous monitoring of both gases simultaneously in N2 gas storage areas, CO2 beverage gas distribution areas, confined spaces, and other locations where low oxygen levels may pose a hazard to personnel. Unlike continuously depleting electrochemical sensor cells, the PureAire Dual O2/CO2 exclusive zirconium cell and patented NDIR cell provide stable oxygen and CO2 readings even in areas where temperature, barometric pressure and humidity levels are changing. The PureAire Dual O2/CO2 oxygen sensor requires no quarterly calibration or annual maintenance and the CO2 sensor automatically adjusts to ambient levels. Just plug it in and leave it alone.

  • Advantages

    No calibration required
    The Dual O2/CO2 Monitor does not require quarterly calibration. The earth is a wonderful source of calibrated oxygen, and under ambient levels, PureAire’s Combo monitor is continuously being challenged to 20.9%. Additionally the ambient earth levels of CO2 are 400ppm. Every week, or on demand, the monitor automatically adjusts to ambient CO2 levels. There are no zero or span adjustments to make or expensive maintenance required.

    Plug & Play Operation
    The Dual O2/CO2 Monitor is ready to go right out of the box. Just mount it to wall or other surface and plug in the power supply into any wall socket. After a 4-minute start-up sequence, the monitor automatically starts operating. It’s designed for unattended 24-7 leak detection for years. Supplied with a full bumper-to-bumper warranty, the Combo O2/CO2 will be the last monitor you’ll need to purchase.

    PureAire’s Dual O2/CO2 monitor installations
    The Dual Monitor is used in restaurants where CO2 and nitrogen are used to dispense beverages and agricultural grow rooms to alert and protect personnel from entering potentially hazardous situations if a leak occurs. Ideal for continuously monitoring oxygen and CO2 levels in confined spaces or areas where inert gases are used, the Dual O2/CO2 Monitor does not drift or loose sensitivity when the weather or temperature changes.

    Dual O2/CO2 monitor Control Features
    The Dual O2/CO2 Monitor has individual dedicated user selectable relays designed to operate on-off valves for the control of CO2 injection in grow rooms while simultaneously activating alarms when oxygen levels get too low. The oxygen sensor can also be used for controlling nitrogen generators for hypobaric rooms while using the CO2 sensor to alarm to TLV levels of carbon dioxide. PureAire uses a sophisticated built-in CPU that provides users with an inexpensive monitor with local display, safety alarms and control for both oxygen and carbon dioxide simultaneously.
