Abstract: Monitoring of atmospheric particulate matter has been greatly attracted by the government, the public and the media. This article introduces the monitoring methods of the atmospheric particulate matter concentration and the new developed auto-monitoring analyzer for particulate matter concentration based on membrane weighing method. By analysis and processing of the particulate matter, the results show that the cutting performance of the analyzer is well. And it realizes the remote real-time monitoring and controlling system by LabVIEW. It is a great help to develop equipments for monitoring particulate matter and the industrialization in our country.
