Pro CO Alarm Analyzer in Waterproof Box


The waterproof box mounted Nuvair Pro CO Alarm analyzer measures carbon monoxide (CO) levels in stored gas cylinders, enclosed spaces and compressors. Alarms for low and high CO content can be set by the user. If the analyzer reading falls below or exceeds alarm setpoints, a small relay sounds an alarm and can illuminate a small LED. This same relay can activate a larger relay to automatically shutdown compressors, sound an external alarm or activate emergency backup systems.

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.
