Long Last Zirconium Sensor

As a leading manufacturer of oxygen monitors, PureAire Monitoring Systems puts safety, performance, reliability, and affordability first. Our oxygen monitors last for 10+ years with no replacement, no scheduled maintenance, and no hidden costs.

These monitors work well anywhere gas leaks would cause oxygen depletion, including in food and beverage, bottling plants,  flash freezing tunnels, laboratories, manufacturing facilities, and freezers. Our monitors are built with a long-lasting zirconium oxide sensor cell, which delivers reliable monitoring against leaks of argon, helium, and nitrogen for 10 years. The Monitor includes audible and visual alarms, but it may be connected to fire alarm systems to amplify the reach.

The O₂ monitor is easy to set up, easy to operate, and requires no calibration once installed. A simple, periodic span adjustment may be necessary. Supervised watchdog software checks that everything is working properly and notifies you of any inconsistencies on the monitor. Immune to performance changes from barometric pressure drops, humidity, and temperature, these monitors are reliable and cost-effective.

Advantages

Connects to Distributive Control Systems and Programmable Logic Controllers 

The AirCheck O₂ Sample Draw Monitor can be used with PureAire’s proprietary controllers, either single or multichannel. Dual selectable alarm relays set off strobe lights and remote horns, so that staff can learn of the hazard. Individuals can operate the oxygen monitors remotely by as much as 1,000 meters or 0.6 miles from the centralized control systems.

Better Oxygen Sensor Cell

Unlike other oxygen monitors, PureAire’s Air Check O₂ Deficiency Monitor relies upon a Current Limiting Zirconium Oxide Oxygen sensor. This sensor does not need a reference gas and can perform reliably in environments that contain 100 percent nitrogen. The sensitive monitor can tell oxygen levels by percentages, so it can operate in lower-temperature environments than the more frequently used concentration-type cells. The improved cell helps PureAire sensors last for 10+ years.

Once set up, the Air Check O₂ Deficiency Monitor performs reliably with no calibration. The earth provides natural calibrated oxygen, which keeps the O₂ monitor challenged to 20.9 percent. A simple, periodic span adjustment may be necessary. For peace of mind, test the Monitor’s response by subjecting it to nitrogen periodically.

O₂ Monitor System Features

PureAire offers its Air Check O₂ Deficiency Monitor in multiple configurations. Every unit comes with a choice of a low-cost basic display monitor or a full-featured, dual-level monitor with user-selectable alarm relays. When built-in alarm relays are used, the sensor continuously monitors electronics, sensor cells, and sample flows. Any faulty information is provided to the front panel LED, mA output, and alarm relay, for instant notification.
