PureAir 99028 MONITORING SYSTEMS OXYGEN DEFFICENCY MONITOR REMOTE SENSING

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 30 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. The Air Check O₂ Monitor features a zirconium cell rather than an electrochemical sensor cell, making it more accurate than other oxygen monitors on the market. This O₂ 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!
