PureAire Oxygen Monitor KF25, 0-25% 99035
PureAire Oxygen Monitor KF25, 0-25% with 10+ Year Sensor 99035
Product Summary
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 vacuum chamber with the use of a KF type vacuum fitting. The monitor is also well suited for semiconductor tools, OLED manufacturers and, for any industry applications where inert gases including, but not limited to, nitrogen, and argon are used in a vacuum. PureAire’s stable, long-life zirconium oxide sensor will last 10+ years in maintained environments without needing to be replaced.

The AirCheck O2 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, the AirCheck O2 zirconium cell provides stable oxygen readings even in areas where temperature and humidity levels are changing. And, the AirCheck O2 is one of the only monitors suitable 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 AirCheck unique sensor mounts directly into chambers or load locks through the use of a KF type vacuum fitting. Monitoring oxygen directly under vacuum eliminates the need to change the environment back to ambient and can improve thru put. The AirCheck O2 Deficiency Monitor also provides stable readings even in areas that contain high electromagnetic fields.

Advantages
Connects to DCS and PLC Controls
The AirCheck O2 Deficiency Monitor is 24 V DC powered and transmits continuous oxygen concentration levels to any distributive control system or programmable logic controller.
PureAire’s Oxygen Sensor Cell
The AirCheck O2 Deficiency Monitor uses an exclusive Current Limiting Zirconium Oxide Oxygen sensor that never requires a reference gas. Unlike concentration type zirconium cells that must have a reference gas, PureAire’s O2 monitor can operate in 100 % nitrogen environments. Capable of detecting 0 % up to 95 % oxygen levels, the current limiting O2 sensor operates at a lower temperature than competitive concentration type cells. The average life of PureAire’s O2 sensor is over 8 years in most environments. The AirCheck O2 Deficiency Monitor never needs calibration. The earth is a wonderful source of calibrated oxygen and under ambient levels; PureAire’s O2 monitor is continuously being challenged to 20.9 %. There are no zero or span adjustments to make; the only optional response test required is to subject the O2 system to nitrogen periodically.
O2 Monitor System Features
The AirCheck O2 Deficiency Monitor is available in many different configurations perfect for OEM process tool installation. PureAire uses a sophisticated built-in CPU that is flexible to provide users with a low-cost basic display only monitor or a full-featured monitor with dual-level, user-selectable alarm relays.
