The handheld Nuvair Pro CO2 Alarm Analyzer measures carbon dioxide levels in breathing gas mixtures and air. Two custom audible and visual alarms for low and high set points. The wall plug-in comes standard but a rechargeable lithium battery is also available. (SKU 9616-LB).
The Nuvair Pro CO2 Alarm Analyzer can be connected inline on your high or low pressure compressor for continuous carbon dioxide monitoring or used periodically on specific gas sources or in contained spaced. The CO2 sensor is auto-calibrating and provides a temperature-compensated, linear CO2 measurement over sensing range.
Audible and visual alarms for low and high carbon dioxide content can be set by the user. If the alarm sounds, the analog output can activate an optional relay that shuts down equipment automatically, sounds a remote alarm, or activates 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.
|Flow Rate||0.6-1 L/min|
|Resolution||50 ppm resolution from 0 to 1000 ppm, then 100 ppm up to full scale|
|Repeatability||± 2% of full scale @ 68°F (20°C) ambient|
|Linearity||At ambient temperature and pressure: ± 2% FSD or ± 10% of the reading, whichever is greater|
|Sensor Type||NDIR (Non-dispersive infrared)|
|Expected Sensor Life||5-10 years based on analyzer handling and use. Check sensor accuracy frequently with test gas and attempt to recalibrate if reading is inaccurate. Replace sensor if recalibration fails.|
