  • Basic Principle of NDIR Gas Detection - Heimann Sensor

    Thermopiles (in combination with an infrared light source) can be used to measure the gas concentration of certain gases. The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law.

  • 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.
