Carbon Dioxide CO2 Measurements | Vaisala

CO 2 is a colorless and odorless gas that is soluble in water. It is the bubbles in the fizzy drink, a greenhouse gas, a byproduct of burning reactions, and in the air we exhale. CO 2 is itself non-combustible and inert gas, which makes reliable measurement challenging. The most dependable method for CO 2 measurements is Vaisala CARBOCAP ® carbon dioxide sensor, an optical infrared ...

ESRL Global Monitoring Laboratory - Mauna Loa Observatory

Carbon Dioxide (CO 2) is measured in parts-per-million (ppm) and reported in units of micromol mol-1 (10-6 mol CO 2 per mol of dry air). Measurements are directly traceable to the WMO CO 2 mole fraction scale. How does this program work? Carbon dioxide (CO 2) in ambient and standard air samples is detected using a non-dispersive infrared (NDIR) ...

How does an NDIR CO2 Sensor Work? |

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.

Carbon Dioxide Detectors & Meters | Edaphic Scientific

The CO2 sensor inside of our CO2 detectors is based on Non-Dispersive Infra-Red (NDIR) technology. NDIR is a low cost approach to measuring carbon dioxide for indoor air quality (IAQ) and HVAC applications. Since it is low cost, some users have questions the accuracy of the sensors. Undoubtedly, there are some NDIR CO2 sensors that are poor ...

Non-Dispersive Infrared, NDIR, Carbon Dioxide Sensors ...

NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared spectroscopy, the principal that molecules absorb specific light frequencies that are characteristic of their structure. When the frequency of the infrared light is the same as the vibration frequency of a bond, absorption occurs.

Measuring Carbon Dioxide (CO ) Using Non-Dispersive ...

Measuring Carbon Dioxide (CO2) Using Non-Dispersive Infared (NDIR) Technology NDIR sensors work using spectroscopy, which pertains to the dispersion of light into its component colors or energies. An example of this is light in the Visible Spectrum (the light humans can see), which is made up of a wide range of wavelengths (~390nm-700nm).
