Pro CO Analyzer

Panel Mount
The Nuvair Pro CO Alarm panel mount analyzer is designed for installation on a control panel or other flat surface for flush mounting. The analyzer connects in-line to high or low pressure compressors for continuous monitoring of carbon monoxide contaminants in the system. Equipped with audio and visual alarms.

Designed for installation on a compressor control panel or other flat surface, the Nuvair Pro CO Alarm panel mount analyzer measures carbon monoxide levels in breathing gas mixtures or air.

Audible and visual alarms for low and high carbon monoxide 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.


Designed to detect the presence of carbon monoxide in stored gas cylinders, enclosed spaces and compressors, the handheld Nuvair Pro CO Alarm analyzer comes with two user-programmable alarms. If the analyzer reading drops below or rises above the alarm set-points, 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.

PLEASE NOTE: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death. 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.
