Water-Resistant Dual O2/CO2 Monitor, 0-25% and 10,000 ppm

The Water-Resistant Sample Draw Dual O2/CO2 Monitor is a self-contained system that is designed for continuous monitoring of inert gases in confined spaces that require daily wash-downs. The monitor can sample O2/CO2 levels from up to 100 feet away and is ideal for facilities that use inert gases including, but not limited to, nitrogen, helium, and argon. Its IP67 water-resistant enclosure keeps the monitor dry during wash-downs. The O2/CO2 monitor is perfect for environments such as breweries, bottling plants, food processing facilities, and laboratories. The monitor will remain accurate at temperatures as low as -40C. PureAire’s durable, zirconium oxide sensor cells, and NDIR cells, will last up to 10+ years in a normal environment, without needing to be replaced.

Long-Lasting Sensors

The PureAire Water-Resistant Combo O2/CO2 Monitor is a compact gas monitoring system that’s ideal for the continuous monitoring of both gases. The monitor is intended for use in nitrogen gas areas, or CO2 food and beverage, confined spaces, and other locations where low oxygen levels may pose a hazard to personnel.

The PureAire Water-Resistant Combo O2/CO2 is made with a proprietary zirconium cell and patented NDIR cell, rather than a continuously depleting electrochemical sensor cell. The zirconium cell means the monitor can provide stable oxygen and CO2 readings despite changes in temperature, barometric pressure, and humidity levels.

The PureAire Combo O2/CO2 oxygen sensor requires no quarterly calibration or annual maintenance and the CO2 sensor automatically adjusts to ambient levels. All you need to do is plug in the monitor and let it run in the background—no scheduled maintenance is required.
