Long-Lasting O2 Zirconium Sensor
Oxygen deficiency monitors are devices designed to measure the oxygen concentration in the ambient air and provide a real-time oxygen reading. The PureAire Oxygen Deficiency Depletion Monitor features a long-lasting zirconium oxide sensor capable of providing accurate readings for 10+ years with no scheduled maintenance, and the Monitor comes with a full 3-year warranty.
What is an Oxygen Deficiency Monitor?
PureAire’s O2 Deficiency Monitor is suitable for a wide range of uses. From bars and restaurants to tire repair centers, food processing plants, laboratories, and hospitals, our Oxygen Monitors ensure that nitrogen and CO2 gas are safely used and that any leaks are detected before human safety is jeopardized. Our zirconium O2 sensor performs reliably in temperatures ranging from 60 Celsius to -40 Celsius, so it’s ideal for environments including freezers, cryogenic facilities, and frozen food manufacturing plants. The low-maintenance and long-lasting sensor provides continuous monitoring in applications in which inert nitrogen gas and CO2 gas are stored. Once set up, the O2 zirconium sensor will operate continuously. So long as everything is operating properly, the Monitor stays silent, but if oxygen levels fall to the OSHA action level, defined as 19.5%, the Monitor’s built-in horn will sound, alerting employees to danger.
One-Step Sensor Adjustment
PureAire Oxygen Deficiency Monitors require occasional testing with nitrogen to validate the sensor’s response to low oxygen levels. While calibration is not necessary for our monitors to accurately measure oxygen depletion levels1, annual fine-tuning might be needed to ensure the sensor’s span accurately corresponds to the standard 20.9% oxygen concentrations.
PureAire’s Auto-Span not only simplifies the process of adjusting the span of the oxygen sensor but also provides a quick check of the sensor and the monitor’s response to an oxygen-deficient atmosphere. With a press of a button, this feature saves you time and money, protects your facilities and employees, and, most importantly, provides you with the reassurance of consistently reliable performance, making it a valuable addition to your safety measures.

Plug & Play Setup
PureAire’s O2 Deficiency Monitor mounts in minutes, and it is ready to go right out of the box. Simply mount the unit on the wall in a location where oxygen needs to be monitored, plug it into the power supply, and power on the unit. After four minutes, the Monitor will begin sampling oxygen levels, which are continuously displayed on the Monitor’s screen, ensuring readily available observation at all times. Our customers appreciate a reliable oxygen sensor that is easy to use and read, and that operates 24/7, with no oversight or scheduled maintenance necessary, for up to 10 years.
PureAire O2 Deficiency Monitor Features
To suit the needs of the user, the PureAire O2 Deficiency Depletion Monitor comes in a range of configurations. Every unit comes with a full-featured, dual-level monitor, options for alarm relays, and hysteresis to account for supply valves for CO2 and nitrogen. All units have a built-in CPU that houses the monitor, display, and alarm
