PureAire AirCheck O2 Sample Draw Oxygen Monitor

PureAire’s Sample Draw Oxygen Monitor is the ideal choice for remote oxygen monitoring in confined spaces, storage areas, and other hard-to-access locations. Equipped with a built-in pump, the system draws air samples from up to 100 feet away — perfect for environments where direct sensor placement isn’t feasible.

Designed for facilities that handle inert gases such as nitrogen, helium, or argon, this monitor is well-suited for MRI rooms, food and beverage production areas, laboratories, cryogenic storage, and other oxygen-sensitive locations.

Built to perform in extreme conditions, the monitor remains accurate at temperatures as low as -40°C. Its core is PureAire’s advanced zirconium oxide sensor, which operates continuously for 10+ years without replacement or routine scheduled maintenance — delivering long-term reliability with minimal upkeep.

Available in 0–25% and 0–95% ranges, with or without horn, and with domestic or global power supplies — choose your configuration above.
