A review on non-dispersive infrared gas sensors ...

Aug 01, 2016· Infrared spectroscopy is a technique based on the vibrations of the atoms of a molecule. An infrared spectrum is commonly obtained by passing infrared radiation through a sample and determining what fraction of the incident radiation is absorbed at a particular energy .As an application of infrared spectroscopy, non-dispersive infrared (NDIR) gas measurement started in the late 1930s in …

What is CO2? | CO2 Sensors | PRODUCTS | Asahi Kasei ...

However, CO₂ can also have negative effects. The higher the concentration of greenhouse gases, the more IR radiation that is absorbed. This IR radiation remains close to the earth's surface, increasing its temperature. Carbon dioxide accumulates in the atmosphere, so it has a warming effect that can affect the global climate.

Carbon Dioxide Health Hazard Information Sheet

What are the health effects of carbon dioxide? CO2 is considered to be minimally toxic by inhalation. The primary health effects caused by CO2 are the result of its behavior as a simple asphyxiant. A simple asphyxiant is a gas which reduces or displaces the normal oxygen in breathing air.
