11.1 Pro CO Analyzer Controls
11.2 Pro CO Display
11.3 Pro CO Alarm
The Analyzer includes an audible alarm that is activated when the Sensor reaches 10 ppm
CO or user programmed level. The alarm will not clear until the concentration of CO drops
below 10 ppm or user programmed level.
11.4 Pro CO Sensor
The Analyzer uses an electrochemical CO Sensor to measure CO content in gases. The
Sensor is disposable and user-replaceable, with a life expectancy of up to 24 months
depending on usage. The Sensor is designed for use at atmospheric pressure (0 psi). The
gas mixture to be analyzed must be regulated accordingly, and any potential for pressure or
vacuum must be avoided.
11.5 Pro CO Calibration
Verify calibration on a weekly basis, or when the ambient temperature or moisture changes
dramatically. Breathing gas applications require the use of a certified CO calibration gas and
flow rate of 1.0-5.0 L/min. The equipment to produce this flow is available from Nuvair. See
Spares and Accessories section.
To assure the greatest accuracy for other applications, use the calibration gas concentration
closest to the expected concentration in the gas being measured.
