Overview

Oxygen deficiency monitor with remote sensor is engineered for facilities that utilize inert gases such as nitrogen, helium, and argon, where the risk of oxygen displacement can pose serious safety threats. The remote sensor extends monitoring capability up to 30 feet from the main unit, making it ideal for cryogenic freezers, storage tanks, and confined spaces where personnel may be exposed to invisible asphyxiation hazards. Whether in low-traffic zones or hard-to-access mechanical rooms, this oxygen deficiency monitor with remote sensor delivers uninterrupted protection and peace of mind.

The monitor features a non-depleting zirconium oxide sensor that operates for over a decade without replacement or scheduled maintenance, even in environments as cold as -40°C. Trusted across industries such as pharmaceutical manufacturing, semiconductor fabrication, food and beverage processing, chemical storage, aerospace, and additive manufacturing, the oxygen deficiency monitor with remote sensor ensures continuous monitoring with minimal maintenance. In environments where inert gases are used in enclosed areas, PureAire's monitor provides essential, around-the-clock safety.

The oxygen deficiency monitor with remote sensor features a high-performance zirconium oxide oxygen sensor, designed for rapid detection of oxygen deficiency and long-term operation in demanding environments. This sensor responds to low oxygen levels within seconds and maintains accurate readings across a wide temperature and humidity range. Unlike disposable sensors that degrade over time and require frequent replacement, the zirconium sensor runs maintenance-free for over 10 years, offering unmatched reliability and peace of mind.

There are no zero or span calibration adjustments required, significantly reducing downtime and labor costs.

For environments that use nitrogen, helium, or argon in confined spaces, an oxygen deficiency monitor with remote sensor provides critical, continuous protection. Understanding oxygen exposure thresholds in confined spaces is essential when choosing the right monitoring system for your facility.
