Product Specification

Sample Draw Oxygen Monitor with 10+ Year Sensor
Item #: TX-1100SAM (99029)

Sample Draw Oxygen Monitor Product Summary
Our Air Check O2 sample draw monitor is a specialized version of our oxygen deficiency monitor perfect for situations where the monitor cannot physically be in the concerning area. The monitor can reside up to 100ft away from the area to be tested and uses a polyurethane or equivalent 1/4 inch tube to draw the sample. For a sterile environment, this monitor is the solution. This has a 10+ year zirconium oxide sensor.

Sample Draw Oxygen Monitor Features
• Suitable for remote sampling to 100 feet
• No maintenance Zirconium cell
• No calibration required
• 3 year warranty
• No drift to environmental or temperature changes
• 10 + year Sensor life
• Local display
• 4-20 mA analog output.
• Built-in flow sample pump
• Built-in user adjustable alarms & relays
• Optional built-in audio horn

The Air check O2 Deficiency Monitor is a compact sample draw gas monitoring system that's ideal for the continuous monitoring of inert gas storage areas, confined spaces, and other locations where low oxygen levels may pose a hazard to personnel. Unlike electrochemical sensor cells the Air check's zirconium oxygen cell provides stable readings even in areas where temperature and humidity levels are changing. The PureAire Air check O2  Deficiency Monitor is suitable for either indoor or
outdoor use.

The heart of the monitoring system is a long lasting zirconium sensor, which responds to low oxygen conditions within seconds and provides accurate and linear concentration readings over the entire measurement range. PureAire's 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!

The monitor's built-in pump is ideal for continuously monitoring oxygen levels in remote confined spaces or under floor areas where inert gases are used. The Air check O2 Sample Draw Monitor does not drift or loose sensitivity when the weather or temperature changes.
