Why does my CO2 sensor read zero after calibration?

The Carbon Dioxide IR sensor is calibration sensitive it needs to have a twopoint calibration performed in the proper order. Zero calibration with 100% Nitrogen gas, zero air or any gas matrix that does not have CO2 to calibrate your baseline. Span calibration with 5000ppm (5%) CO2 gas. The 5000ppm Span value is the lowest span value that the sensor will calibrate properly to. If you skip the ...

Infrared Carbon Dioxide Sensors

The sensor requires a twopoint calibration. First, the carbon dioxide sensor must be zeroed. This is performed by flowing a gas without carbon dioxide through the analyzer and adjusting the zero on the analyzer. Second, the span needs to be adjusted. A span gas containing an amount of carbon dioxide close to the concentration of carbon dioxide found in the sample gas should be used to span ...

Calibration device for carbon dioxide sensor Honeywell ...

However, if the instrument is in a difficult position to service, or if calibration of the carbon dioxide sensor is not otherwise freely available, it is often impossible to confirm that the carbon dioxide sensor is functioning correctly. Therefore, as the carbon dioxide sensor reaches the end of its working life, the output of the sensing cell may be insufficient to generate an alarm or other ...

Calibration of carbon dioxide sensors

To calibrate using outside air, take your sensor to an outside area away from running vehicles, people, animals, and other carbon dioxide sources. Let the sensor carbon dioxide value settle for about 20 minutes. (Since human breathing creates a significant amount of carbon dioxide, for best results leave the sensor during this time.) Then follow the steps above for calibrating the sensor using the outside air carbon dioxide …
