Pro O2 Alarm Analyzer Handheld

$466.00

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 (O2) 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. Three power and two module options.

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.

Available Options

Three power options are available for this analyzer: 110/220V wall plug-in, 9-volt battery, and rechargeable lithium battery. For wall plug-in powered analyzers, two optional modules can be built into your analyzer: FAILSAFE and SMART START.

Adding the FAILSAFE Module to your Nuvair Pro Alarm analyzer will automatically disable integrated power equipment if: (a) Analyzer power is interrupted, or (b) Analyzer goes into alarm. Adding a SMART START Module to your Nuvair Pro Alarm Analyzer will automatically power-up the analyzer in tandem with integrated power equipment, like a compressor.

Choose one of three available power options and two available module upgrades by using the Power & Module Options dropdown menu (above).
