CO analyzer adopts non-dispersive infrared spectrum and combines with advanced microprocessor technology. It provides accurate and reliable detection of CO at ppm level to meet the requirement of ambient gas monitoring. The principle is non-dispersive infrared based on gas filter correlation technology. CO molecule absorbs specific infrared light which is consistent with Beer-Lambert principle. CO concentration can be obtained by comparing infrared energy adsorption by sampling gas and reference gas. This analyzer can completely control all functions and also provides online instruction for important work parameters. Real time auto compensation for temperature and pressure will be made during measurement.
