In order to resolve the problem of the traditional infrared gas analyzer

such as poor stability and low measurement precision

a new gas analyzer is designed based on non-dispersive infrared absorption principle.The emphasis is paid on the analysis of pulsed infrared source

thermopile infrared detector

light and gas path structure

signal regulating circuit and embedded real-time monitoring system.The industrial ethernet interface is designed using ethernet controller CP2200

measurement and alarm information is sent quickly and accurately by the ethernet interface.Experimental results have proved that this infrared gas analyzer has the characteristics of fast response

high measurement precision

good stability and has a high practical value.
