Dual O2/CO2 Monitor, 0-25% and 0-50,000ppm

This dual-sensor monitor is designed for use in areas containing Nitrogen, Carbon Dioxide, Argon, and mixed cryogenic gases. It includes all of the top-of-the-line features of our air check oxygen deficiency monitor, though it monitors the level of CO2 in the room as well. It is ideal for use in environments such as breweries, laboratories, universities, bottling plants, pharmaceutical manufacturing facilities, or CO2 marijuana extraction. This monitor contains a 10+ year zirconium oxide sensor.

PureAire Monitoring System’s Dual O2/CO2 Monitor provides continuous monitoring of oxygen and carbon dioxide. This monitor is ideal for use in confined spaces where low oxygen concentrations could pose a health hazard, from nitrogen gas storage sites to carbon dioxide beverage gas distribution areas.

While many O2/CO2 meters rely on electrochemical sensor cells, PureAire developed its Dual O2/CO2 Monitor with a zirconium oxide and NDIR cell. This cell is impermeable to changing barometric pressure, storms, temperatures, and humidity, for reliable performance across a range of atmospheric conditions. While other units require quarterly calibration and periodic maintenance, PureAire’s Dual O2/CO2 Monitor needs no scheduled maintenance or calibration once installed. If you seek an O2/CO2 monitor that you can plug in, leave alone, and rely on to monitor oxygen and carbon dioxide levels, try PureAire.
