CO2 can be measured using photoacoustic spectroscopy. Concentration of CO2 can be measured by subjecting a sample to pulses of electromagnetic energy (such as from a distributed feedback laser ) that is tuned specifically to the absorption wavelength of CO2. With each pulse of energy, the CO2 molecules within the sample will absorb and generate pressure waves via the photoacoustic effect. These pressure waves are then detected with an acoustic detector and co… Most modern carbon dioxide detectors use non-dispersive infrared (NDIR) sensors that measures infrared light in a sample of air. This technology is useful as the amount of light that passes through the sample is inversely proportional to the number of carbon dioxide molecules in the air. As IR light passes … See more Depending on your industry, environment, and use of stored gases, you may need a carbon dioxide detector.
