Based on laser energy absorption ratio differential algorithm methane concentration detection system
To reduce the interference of other gases and improve the detection accuracy in CH4 concentration detection, a CH4 concentration detection system is proposed, and a ratio differential algorithm is designed. The difference value of the absorbed light intensity between chamber 1 and chamber 2 used to...
