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 replacing of the sensor for 10+ years.
The O2 monitor is used in laboratories using Nitrogen, Helium, and Argon. The monitor is also used in confined spaces, hyperbaric chambers, cryogenic gas storage areas, and freezers. The Air Check oxygen Monitor uses a long-lasting zirconium oxide sensor and 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 maintenance or calibration due to its non-depleting 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 in replaceable sensors.
