The most also do not carry out PM2.5Monitoring, mostly only to PM10It is monitored.At present, PM2.5The monitoring method of three kinds of main flows has
Oscillating balance method, the method quantitative relationship is clear and definite, and shortcoming is that measurement result is on the low side, need to install film dynamic measurement system additional；β ray
Method is generally acknowledged to determination data and there is deviation；Light scattering method mainly measures PM2.5Number concentration, by number concentration convert
After the mass concentration needed for environmental protection part, its accuracy can decline to a great extent.Above-mentioned three kinds of methods operation complexity, measurement result is accurate
Exactness is the highest, and instrument involves great expense.
Therefore, research design one can monitor PM in air simultaneously2.5、PM10With the mass concentration of TSP, operation letter
The atmosphere particle monitoring device that list, low cost, accuracy of measurement are high has long-range application prospect and practical significance.
