Product Summary

PureAire’s Oxygen Deficiency Monitor with Remote Sensor is perfect for facilities that use inert gases, including, but not limited to, nitrogen, helium, and argon. The remote sensor allows for continuous monitoring up to 10 feet from the monitor. This monitor is well suited for confined spaces or spaces that are not easily accessible. The monitor will remain accurate at temperatures as low as -40C. PureAire’s durable, non-depleting, zirconium oxide sensor will last up to 10+ years in a normal environment without needing to be replaced.

The AirCheck O2 Monitor with a remote sensor is ideal for use in confined spaces, such as gas storage rooms or freezers. Since the Air Check O2 Monitor features a zirconium cell rather than an electrochemical sensor cell, it is more accurate than other oxygen monitors on the market. This O2 monitor can be used indoors or outdoors and provides accurate readings despite changes to temperature, barometric pressure, and humidity.

The heart of the monitoring system is a long-lasting zirconium sensor, which responds to low oxygen conditions within seconds and provides accurate measurements over a wide temperature and humidity range. The zirconium O2 sensor cell will operate continuously for 10 or more years and requires an absolute minimum of maintenance. There are no zero or span calibration pots to adjust and when compared to disposable type sensors, our long-life zirconium O2 sensor can save up to $475 annually and will pay for itself in just over 3 years!

Connects to SCADA and PLC Controls

The AirCheck O2 Deficiency Monitor checks oxygen concentration levels and transmits readings to any programmable logic controller or system control data acquisition system. The O2 sensor can work with your existing equipment to save on implementation costs. The AirCheck O2 Deficiency Monitor may be operated remotely via a centralized controller at distances of up to 1,000 meters (0.6 miles), for flexibility.

No Reference Gas Necessary

Oxygen monitors that use a concentration type zirconium cell require a reference gas to work properly, but the Air Check O2 Deficiency Monitor provides reliable readouts with no reference gas. Unlike oxygen sensors from other manufacturers, PureAire’s monitors can be used in 100 percent nitrogen environments and at lower temperatures. The AirCheck O2 Deficiency Monitor can detect oxygen levels from 0 to 25 percent with no calibration and no maintenance for a period of 10 years or longer.

No Calibration Necessary

As mentioned, once installed this O2 monitor needs no calibration to perform reliably. The AirCheck O2 Deficiency Monitor receives a continuous challenge from the earth’s natural supply of calibrated oxygen. What does this mean for you? No adjustments to make, no annual maintenance or calibration, and no worry. For peace of mind, you may wish to expose the oxygen monitor to nitrogen periodically, both to challenge the system and familiarize staff with what happens when the oxygen monitor’s alarm goes off. This way, everyone knows what to do if there’s an oxygen shortage.
