PureAire Monitoring Systems is a leading manufacturer of O2 monitors. We created a better product that eliminates the inconvenience of disposable sensors while continuing to meet your needs. When it comes to O2 deficiency detection, PureAire makes the longest-lasting, most reliable, and affordable oxygen monitors. There are no hidden costs and no replacement of the sensor for 10+ years.

The O2 monitor is used in laboratories using Nitrogen, and Argon. The monitor is also used in confined spaces, glove boxes, incubators, gas hoods, cryogenic gas storage, and research and development. PureAire Oxygen Monitors are built with a long-lasting zirconium oxide sensor cell that responds to changing conditions within seconds at temperatures down to -40C.

Easy to operate, the O2 monitor‘s joystick controls an audible alarm with visual alarm indicators. The instrument uses a local display and can be linked to fire alarm systems.

The monitor requires no scheduled maintenance or calibration due to its long-life sensor. Built-in “supervised watchdog” software continuously monitors all instrument functions 24/7. PureAire’s Oxygen Monitor is not affected by humidity, temperature, or changes in barometric pressure. Rapidly changing barometric pressure from thunderstorms will not disrupt PureAire’s oxygen deficiency monitor. The majority of oxygen monitors sold use depleting electrochemical sensors that require frequent maintenance and calibration. PureAire’s Oxygen monitor can save up to $400 annually on replaceable sensors.

Connects to SCADA and PLC Controls

The Air check O2 Deficiency Monitor is 24VDC powered and transmits continuous oxygen concentration levels to any system control data acquisition system, or programmable logic controller. The PureAire’s Oxygen Deficiency Monitor can also be operated remotely up to 1,000 meters or 0.6 miles from centralized controllers.

PureAire’s Oxygen Sensor Cell

The Air check O2 Deficiency Monitor uses an exclusive Current Limiting Zirconium Oxide Oxygen sensor that never requires a reference gas. Unlike concentration-type zirconium cells that must have a reference gas, PureAire’s O2 monitor can operate in 100% nitrogen environments. Capable of detecting 0% up to 95% oxygen levels, the current limiting O2 sensor operates at a lower temperature than competitive concentration type cells. The average life of PureAire’s O2 sensor is over 10 years in most environments.
The Air check O2 Deficiency Monitor never needs calibration. The earth is a wonderful source of calibrated oxygen and under ambient levels; PureAire’s O2 monitor is continuously being challenged to 20.9%. A simple, periodic span adjustment may be necessary. The only optional response test required is to subject the O2 system to nitrogen periodically.

O2 Monitor System Features

The Air check O2 Deficiency Monitor is available in many different configurations. PureAire uses a sophisticated built-in CPU that is flexible to provide users with a low-cost basic display-only monitor or a full-featured monitor with dual-level, user-selectable alarm relays. Other options available are Modbus digital communications or full Wireless radio communications.
