Pro CO2 Alarm Analyzer in Waterproof Box
This version of the Nuvair Pro CO2 alarm analyzer comes mounted in a weatherproof box. Two custom audible and visual alarms for low and high carbon dioxide set points. Verify stored gas cylinder contents, monitor an enclosed space or connect to a compressor for continuous analysis.
The Nuvair Pro CO2 alarm analyzer measures carbon dioxide levels in all breathing gas mixes and is designed to verify CO2 concentration in stored gas cylinders, monitor an enclosed space, or analyze continuous flow gas from a compressor. Mounted in a weatherproof box, the analyzer is moisture and impact resistant and is compatible with outdoor and marine environments.
Two audible and visual alarms for low and high carbon dioxide content can be user-defined. If the alarm sounds, the analog output can activate an optional relay that shuts down power equipment, sounds remote alarms, or activates emergency backup systems.

* All specifications are at ambient/sea level, 77°F (25°C) and are subject to change without notice.
Calibration must be confirmed with a calibration CO2 test gas.
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.
