This product is mainly used to measure the concentration of particles in the air can be inhaled, which is usually PM2.5, by the way, the functional measurement of air temperature, humidity, using laser technology to measure, very sensitive.
\nFine particles, also known as fine particles, fine particles PM2.5. Refers to fine particles in ambient air, aerodynamically equivalent particle diameter less than or equal to 2.5 microns. It was suspended in the air for a longer time, the higher the concentration of its content in the air, due to more serious air pollution.<\/p>\n
Although the Earth's atmospheric composition of PM2.5 is only a few components in content, air quality and visibility have an important impact. Compared with coarse atmospheric particles, the particle size of PM2.5 is small, large surface area, active, easily accidental toxic and dangerous substances (such as heavy metals, microorganisms, etc.), and a long time of staying in the atmosphere, the transmission distance, therefore larger impact on human health and environmental quality of the atmosphere.<\/p>\n
