| Abstract: | According to new ambient air quality standards,the monitoring items of particulate include PM10 and PM2.5.Beta ray attenuation is a common principle of particulate matter automatic monitor.BAM-1020 continuous particulate monitor of Met One Instruments Inc. is one representative instrument of this principle.Nowadays the introduction regarding the construction and maintenance of this instrument is so poor that many problems exist in safe operation and data reliability.This paper describes some problems appeared in the construction and maintenance of this instrument.This paper also gives some maintenance experiences and precautions.We hope to provide some references for technicians and the basic technical assurance for the operation stability and data quality. |
