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 Beer-Lambert 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 …

Nondispersive Infrared Sensor - Assignment Point

NDIR is an industry term for “nondispersive infrared”, and is the most common type of sensor used to measure carbon dioxide or CO2. Infrared (IR) techniques are very popular in gas detection technology since many gases have characteristic vibration/rotation absorption spectra with narrow, non-overlapping bands in the infrared spectrum between 2 μm and 20 μm. Non-dispersive type infrared absorption …
