|The principles of online monitoring equipment for stationary source particulate matter were studied in 2019 in Jinan City, and online monitoring was compared with manual monitoring as well. The results showed that the results of four on line particle monitoring devices based on laser forward scattering method were in good agreement with manual monitoring results, and sampling head with heating function can effectively reduce the interference of water droplets; while the result of on line particle monitoring equipment based on laser back scattering method showed less consistent with manual monitoring results, the zero drift reached a value of 3.3%, and the absolute error of 2/3 manual comparison results were >±5 mg/m3. The equipment based on laser back scattering method is not suitable for ultra low emission enterprises. The equipment based on laser forward scattering method is suitable for high humidity and low range environments, and has high measurement accuracy, and has better applicability in Jinan City.
