The Pro CO
2
can be used to monitor an enclosed space or to analyze a regulated gas sample
flow, the contents of a gas cylinder, or the flow from a regulator:
•
If monitoring an enclosed space, simply remove the Flow Adapter Cap to expose the Sensor
face to the atmosphere and allow 15 seconds for the Display reading to stabilize.
•
If analyzing a gas flow, the Sample Flow Method is the preferred method. The flow rate
must equal 1.0-5.0 L/min at atmospheric pressure (1 bar). To produce this flow, a Flow
Restrictor and Regulator may be required. Contact Nuvair if you need assistance.

Sample Flow Method of Checking Calibration (Preferred)
1) Turn on Analyzer with air only flowing through the
Analyzer Trio. Once the analyzer has stabilized you
can move on to step 2.
2) Turn the Analyzer off.
3) Attach a Certified calibration gas that best matches
The gas you will be using with the Analyzer Trio and Open
gas line to send a 1.0-5.0 L/min flow to the sensor.
4) Turn on the Analyzer and allow reading to stabilize.
Record reading and compare to test gas spec.
Once testing is complete and calibration is verified you are able to proceed with using the
analyzer.
Nuvair offers CO
2
gas testing kits see addendum for more information.
Testing Gas must not contain Helium for calibration to succeed.
