PureAire Monitoring System’s Dual Oxygen/Carbon Dioxide 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 monitors 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.

Advantages

No Calibration Required

Unlike other oxygen monitors, PureAire’s Dual O₂/CO₂ Monitor does not require quarterly calibration. The earth provides calibrated oxygen to challenge the Dual O₂/CO₂ Monitor to 20.9 percent oxygen and 400 ppm CO₂ under ambient conditions. On a weekly basis, the monitor automatically recalibrates to the ambient CO₂ level for reliable performance. The monitor needs no adjustments and no scheduled maintenance once installed, for truly maintenance-free O₂/CO₂ detection.

Plug & Play Setup

PureAire’s Dual O₂/CO₂ Monitor is ready to work the moment you take it out of the box and mount it. All you need to do is remove the unit, mount it to a wall or another surface, and connect the power supply to a socket. The monitor takes four minutes to start up, then begins operating automatically. Once set up, the Dual O₂/CO₂ Monitor provides non-stop, leak detection for years. Our bumper-to-bumper warranty makes the Dual O₂/CO₂ Monitor the last monitor you’ll ever need to purchase.

PureAire’s Dual O₂/CO₂ Monitor Installations

PureAire’s Dual O₂/CO₂ Monitor is ideal for a range of installations. Place one in restaurants, fast food outlets, bars, and anywhere that N₂ and CO₂ are used to dispense carbonated beverages. Or use it in an agricultural grow room, laboratory, or other places where inert gases could pose a health hazard if a leak occurs. PureAire’s Dual O₂/CO₂ Monitor never drifts or loses sensitivity when weather, barometric pressure, or temperature changes, so you can rely on it to work properly at all times.

Dual O₂/CO₂ Monitor Control Features

PureAire’s Dual O₂/CO₂ Monitor comes with user-selectable relays that connect to on-off valves, which control CO₂ injection and simultaneously activate alarms when oxygen levels fall below the OSHA threshold. The oxygen sensor can also check carbon dioxide levels and control nitrogen generators in hypobaric rooms. PureAire’s Dual O₂/CO₂ Monitor features an inexpensive monitor that has a local display, separate controls for oxygen and carbon dioxide, safety alarms, and a built-in CPU.
