How does an NDIR CO2 Sensor Work? |

January 05, 2021 NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.

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.

Infrared Carbon Dioxide Sensors -

Calibration of infrared carbon dioxide sensors. The sensor requires a two-point 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 ...
