How does an NDIR CO2 Sensor Work? |

Like every IR gas sensor, the analyzer at Mauna Loa used the same basic principle for measuring CO2. It has an infrared light radiation source at one end of a gas sample tube and an IR detector at the other. The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount ...

Thermal Conductivity versus Infrared CO2 Sensors | Blog ...

2018-10-06· The CO2Cell Incubator and the SCO Air Jacket CO2 Incubator both utilize IR sensors. The sensor can detect how much CO 2 is in the atmosphere by measuring how much μm light passes through it. The big difference here is that the amount of light detected is not dependent on any other factors, such as temperature and humidity, as is the case with thermal resistance. This means you can …

Why does my CO2 sensor read zero after calibration?

The Carbon Dioxide IR sensor is calibration sensitive it needs to have a two-point 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 ...
