NDIR CO2 Sensor produce in Europe

Introduction to Gas Sensing Using Non-Dispersive Infrared (NDIR)

Carbon-dioxide infrared spectrum. Figure 3. Methane infrared spectrum. IR reacts with the gas only when a dipole on the molecule is created. Molecular dipoles can occur when the vibration modes are non-symmetrical or when atoms in the molecules are organized in a non-symmetrical fashion. The vibrations comprise bending and stretching of the molecules that deform them to produce dipole or multi-pole …

How does an NDIR CO2 Sensor Work? |

Serial output is especially useful for using NDIR CO2 sensors with ... For years, high-end gas analyzers have been produced based on photoacoustic spectroscopy, or PAS. PAS is was discovered by Alexander Graham Bell in the 1880s. He noted that strobed sunlight shown on different materials produced an audible sound. Since PAS systems do not rely on the length of the waveguide, an even …
