The most advanced Non-Dispersive Infrared (NDIR) Gas Analyzer available

1530 Series Infared/Oxygen Gas AnalyzerThe 1530 Series Cemtrex IntelliCEMS Infrared/O2 Multi-Component Analyzer 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 pass 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. The detector is filled with the gas component of interest and consequently the beam experiences further energy absorption. This absorption process increases the pressure in both of the chambers. The differential pressure between the front and rear chambers of the detector causes a slight gas flow between the two chambers. This flow is detected by a mass-flow sensor and is converted into an output signal.
