The handheld Nuvair Pro O2 Alarm Analyzer is easy to operate and rugged. Users can set two audible/visible alarms for high and low oxygen percentages. When the alarm sounds, the analog output can activate an optional relay that automatically shuts down compressors, sounds an alarm, or activates a back-up system.
Easy to operate, extremely accurate and stable, the handheld Nuvair Pro O2 Alarm Analyzer is preferred by commercial, military, technical and advanced recreational divers using nitrox and non-divers who require a simple oxygen analysis of compressed gas or contained spaces. Audible and visual alarms for low and high oxygen content can be set by the user. If the alarm sounds, the analog output can activate an optional relay that shuts down compressors automatically, sounds a remote alarm, or activates an emergency backup system. Price varies according to power options.
Our water- and impact-resistant case is designed for everyday use in the marine environment. To change the battery or sensor, simply remove four screws to access user-changeable components. All Nuvair Pro O2 units are built and tested in-house, and are ready to use upon receipt.
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.
