Basic Principle of NDIR Gas Detection Heimann Sensor

+

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 BeerLambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC). Also gases like carbon monoxide (CO) and nitrogen ...
