How to Measure Carbon Dioxide - Vaisala

How to Measure Carbon Dioxide Figure 1. IR absorption of CO 2 and some other gases. the measured gas doesn't directly interact with the sensor, IR sensors can withstand high humidity, dust, dirt, and other harsh conditions. The key components of an IR CO 2 detector are light source, measurement chamber, interference filter, and IR detector.

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 ...

Carbon Dioxide Absorption in the Near Infrared

This experiment explored the absorptivity of four peaks, 1437, 1955, 2013, and 2060 nanometers, in the near-IR (NIR) absorption spectrum of CO 2. The NIR absorption bands in CO 2 can contribute up to 30% of the total solar heating in the mesosphere. Between the heights of 60-85 km the heating can exceed 1 K/day.
