For any gas concentration measurement system, the detection limit is the figure of merit. It characterizes the minimum detectable change in concentration that can be measured. The detection limit for a given NDIR gas monitoring system depends strongly on the measurement setup itself, the gas and its concentration to be measured.

5 mins readNDIR 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.

What is a non-dispersive infrared (NDIR) gas sensor ? Using the characteristics which absorb the specific wavelengths of infrared rays, NDIR sensors measure the ratio of absorbed infrared rays and compute the density of gases. (ex. CO2 absorbs 4.26㎛ and CO absorbs 4.64㎛)
