CAI - Model ZRE NDIR/O2 - Multichannel Analyzer - Brochure

The ZPA analyzer uses NDIR technology to measure CO, C02, CH4, S02, NO and paramagnetic or fuel cell for oxygen. The ZPA NDIR technology is based on the infrared absorption characteristics of gases. Using a single infrared beam to measure gas concentrations, this analyzer produces highly stable and reliable results. A single infrared light beam is modulated by a chopper system and passed through a sample cell of predetermined length containing the gas sample to be analyzed. As the beam passes through the cell, the sample gas absorbs some of its energy. The attenuated beam (transmittance) emerges from the cell and is introduced to the front chamber of a two-chamber infrared microflow detector.
