The Remote Sensor Oxygen Monitor is ideal for use in confined spaces, such as gas storage rooms or freezers. It features a zirconium cell rather than an electrochemical sensor cell, making it more accurate than other oxygen monitors on the market. The Remote Sensor Oxygen Monitor can be used indoors or outdoors and provides accurate readings despite changes in 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 no scheduled 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!
One-Step Sensor Adjustment
PureAire Oxygen Deficiency Monitors require occasional testing with nitrogen to validate the sensor’s response to low oxygen levels. While calibration is not necessary for our monitors to accurately measure oxygen depletion levels1, annual fine-tuning might be needed to ensure the sensor’s span accurately corresponds to the standard 20.9% oxygen concentrations.
PureAire’s Auto-Span not only simplifies the process of adjusting the span of the oxygen sensor but also provides a quick check of the sensor and the monitor’s response to an oxygen-deficient atmosphere. With a press of a button, this feature saves you time and money, protects your facilities and employees, and, most importantly, provides you with the reassurance of consistently reliable performance, making it a valuable addition to your safety measures.
1Please follow your facility’s safety guidelines and state and local regulations regarding calibration requirements for safety equipment.
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 scheduled maintenance for a period of 10 years or longer.
