Oxygen Monitor KF25, 0-25% with 10+ Year Sensor
PureAire’s KF25 0-25% Oxygen Deficiency Monitor is ideal for facilities requiring continuous monitoring of gas lines, glove boxes, nitrogen compressors, and vacuum chambers, as well as any locations where low oxygen levels need to be supervised. The unit’s oxygen sensor mounts directly into the process chamber with the use of a KF-type vacuum fitting. The monitor is also well suited for semiconductor tools, OLED manufacturers, and, for any industrial applications where inert gases including, but not limited to, nitrogen, and argon are used. PureAire’s stable, long-life zirconium oxide sensor will last 10+ years in maintained environments without needing to be replaced.

PureAire’s KF25 Oxygen Monitor is for continuous monitoring of gas lines, 3D printers, glove boxes, nitrogen gas compressors, vacuum chambers, and locations where low oxygen levels need to be monitored. Unlike electrochemical sensor cells, PureAire’s O2 zirconium sensor cell provides stable oxygen readings even in areas where temperature and humidity levels are changing. PureAire’s KF25 Oxygen Monitor is well suited for monitoring directly in a vacuum.
The heart of the monitoring system is a long-lasting zirconium sensor, which detects 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!
The Monitor’s unique sensor mounts directly into chambers or load locks through the use of a KF-type vacuum fitting. Monitoring oxygen directly under a vacuum eliminates the need to change the environment back to ambient and can improve thru put. The Monitor also provides stable readings even in areas that contain high electromagnetic fields.
#99035 - Includes power supply for use in the US, Canada, Mexico, Japan
#99128 - Includes Global power supply w/ interchangeable adaptors
For any industrial applications where inert gases including, but not limited to, nitrogen, and argon are used. PureAire’s stable, long-life zirconium oxide sensor will last 10+ years in maintained environments without needing to be replaced.
