Description

Technical Field

[0001] The utility model relates to the technical field of PM2.5 sampling and monitoring equipment, in particular to an air sampling and monitoring device. Background Art

[0002] PM2.5 generally refers to fine particulate matter, also known as fine particles, fine particles, or PM2.5. Fine particulate matter refers to particles in ambient air with an aerodynamic equivalent diameter of 2.5 microns or less. They can remain suspended in the air for extended periods, and higher concentrations indicate more severe air pollution. Although PM2.5 is a minor component of Earth's atmosphere, it significantly impacts air quality and visibility. Compared to coarser atmospheric particulate matter, PM2.5 particles are smaller, larger, and more reactive, making them more susceptible to toxic and harmful substances (such as heavy metals and microorganisms). They also remain in the atmosphere for longer periods and travel greater distances, resulting in a greater impact on human health and atmospheric environmental quality. The most common methods for measuring PM2.5 are: 1. the oscillating balance method; 2. The beta-attenuation method. All measurements of PM10 and PM2.5 particles use a beta-attenuation detector, also known as a BAM. These are specialized instruments and the only official air quality monitoring instruments used in most countries. At present, the fixed installation process of PM2.5 sampling and monitoring devices is complicated, and often requires the collaboration of multiple people to complete the entire installation process. It consumes a lot of labor and has poor practicality. Summary of the Invention
