Long Lasting Zirconium Sensor

The Oxygen Deficiency Monitor features a zirconium sensor capable of providing accurate readings for 10+ years with little maintenance. This reliable, maintenance free sensor will pay for itself in just two years and save your business as much as $475 per year. Every unit comes with a full 3-year warranty for your peace of mind.

The Air Check O₂ Deficiency Monitor is suitable for a range of uses. From bar and restaurant beverage stations to tire repair centers, food processing plants, and hospitals, oxygen monitors ensure that nitrogen and CO₂gas are safely used and no leaks occur. The zirconium O₂ sensor performs reliably in temperatures ranging from 55 Celsius to -40 Celsius, so it’s ideal for a range of environments, including freezers. The monitor also performs well in basements and other confined spaces.

Once set up, the O₂ zirconium sensor will operate continuously, without calibration or adjustment. The system monitors for any faults and displays errors on the gas concentration screen, so you can respond.

The low maintenance, long lasting sensor provides continuous monitoring in environments where inert nitrogen gas and CO₂ gas are stored. As long as everything is operating properly, the monitor stays silent. If oxygen levels reach the OSHA action level, defined at 19.5 percent, a built-in horn alerts employees of danger.

Advantages

No Calibration Required

While other oxygen deficiency monitors might require semi-annual tune-ups to work properly, the Air Check O₂ Deficiency Monitor provides constant monitoring with no adjustments. This saves you time and money while protecting your organization and delivering peace of mind.

Plug & Play Setup

The Air Check O₂Deficiency Monitor mounts in minutes and is ready to go right out of the box. Simply mount the unit on the wall where you need to monitor oxygen levels, plug it into the power supply, and power on the unit. After four minutes, the monitor begins sampling oxygen levels. Levels display on the screen so you can check whenever you walk by. Enjoy a reliable oxygen sensor that’s easy to use, easy to read, and operates with no attention 24/7 for up to 10 years.

Air Check O₂ Deficiency Monitor Features

To suit user’s needs, the Air Check O₂Deficiency 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.
