Pro O2 Alarm Analyzer - Handheld
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.
