Pro CO2 Alarm Analyzer Handheld
The handheld Nuvair Pro CO2 Alarm Analyzer measures carbon dioxide (CO2) levels in breathing gas mixtures and air. Two (2) customizable audible and visual alarms for low and high set points. Three power options and two module options available.
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.

Available Options
Three power options are available for this analyzer: 110/220V wall plug-in, DIN rail, and lithium battery. For wall plug-in and DIN rail powered analyzers, two optional modules can be built into your analyzer: FAILSAFE and SMART START.
Adding the FAILSAFE Module to your Nuvair Pro Alarm analyzer will automatically disable integrated power equipment if: (a) Analyzer power is interrupted, or (b) Analyzer goes into alarm. Adding a SMART START Module to your Nuvair Pro Alarm Analyzer will automatically power-up the analyzer in tandem with integrated power equipment, like a compressor.
Choose one of three available power options and two available module upgrades by using the Power & Module Options dropdown menu (above).
