Go Direct® CO2 Gas Sensor User Manual – Vernier

Carbon dioxide gas moves in and out of the sensor tube by diffusion through the vent holes in the sensor tube. The sensor uses a small light to generate infrared radiation (IR). The IR source is located at one end of the sensor’s shaft. At the other end of the shaft is an infrared sensor that measures how much radiation gets through the sample without being absorbed by the carbon dioxide molecules. …

Respiratory gas analysis | BJA Education | Oxford Academic

01/02/2009· Carbon dioxide, nitrous oxide, alcohol, water vapour, and carbon monoxide will all absorb infrared between 3 and 12 µm. Modern gas benches look at a series of absorption peaks enabling agent identification. Carbon dioxide and nitrous oxide will broaden each other’s peaks and those of volatile agents (collision broadening). This is where the energy absorbed by one molecule is transferred to …

CO2 Absorption of IR Radiated by the Earth | Journal of Chemical …

01/03/1997· A quantitative experiment which illustrates the absorption by carbon dioxide of infrared light radiated from the earth is described. The experiment is based on a model derived from Beer's Law; the experiment shows that, theoretically, 99% of infrared light in the range from 2390 to 2275 cm-1 radiated from the earth is absorbed in the lowest 25 m of the atmosphere. The experiment should be useful for …

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. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR radiation produced by the lamp …
