NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or 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.
The CO2 measuring principle is based on the dual-beam reference measuring process. As the CO2 concentration in the air increases, more infrared light is absorbed. The electronics unit calculates the CO2 concentration from this and converts it to a 0-10 V signal. Along with the actual CO2 measure- ment on the first channel, a reference is also measured on a second channel.
The AirSense™ Model 400 Infrared CO2 Sensor is the first compact, general purpose OEM CO2 analyzer with state of the art dual-beam CO2 sensing technology was previously available only on the most expensive laboratory-grade instruments: the Model 400 now delivers the high-end performance of dual beam technology at an affordable price.
Single-Beam Dual-Wavelength Sensors Single-beam dual-wavelength sensors don’t suffer from the drift issues that affect the performance of single-beam single-wavelength and dual-beam single-wavelength sensors. This technology, which is commonly used in expensive filter-wheel analyzers, measures not only at the absorption wavelength, but
