Pro O2 Analyzer - Panel Mount


Accurate, stable, and simple to use, the Nuvair Pro O2 Panel Mount Analyzer is preferred by commercial and recreational divers using nitrox and can be used in other industries requiring in-line measurement of oxygen in a mixed gas. The Nuvair Pro O2 Panel Mount Analyzer model easily installs on control panels or other flat surfaces for a flush finish.


Designed for installation on a control panel or other flat surface, the Nuvair Pro O2 panel mount analyzer measures oxygen levels in breathing gas mixtures. The Pro O2 can be used in various disciplines including diving, welding, inerting, medical, and laboratories. Compatible with nitrox, heliox and trimix. Choose from three power options. All Nuvair Pro O2 units are built and tested in-house, and come ready to use.

WARNING: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Most gas analyzers can be used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator. The flow rate of gas must equal 1-5 L/min. To produce this flow, a Flow Restrictor and Regulator may be required. A faulty Flow Restrictor can lead to a false analyzer reading. Flow Restrictors should be regularly tested with a Flow Meter. Inaccurate gas analysis can lead to serious personal injury or death.
