Pro CO Alarm Analyzer w/ Relay in Waterproof Box


Mounted in a waterproof box, Nuvair Pro CO Alarm analyzer with external SPDT relay 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 goes into alarm, a piezo buzzer sounds, the LED alarm light illuminates, and the SPDT relay activates. The included SPDT relay cable (10A @ 230VAC/30VDC ampacity) can connect to auxiliary equipment to trigger external alarms, emergency backup systems, or compressor shutdown. Choose from two power options.

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.
