Carbon Monoxide Analyzer Manual
The Pro CO
2
TM
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 0.5 to 1 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.
