Mengshen® High Sensitive PM2.5 Handheld Particle Counter Air Quality Monitor +/-2%RH With 2.8" TFT Color LCD Display MS-M9601

Description:
This product is mainly used to measure the concentration of particles in the air can be inhaled,which is what we usually PM2.5,incidentally,functional measurement of air temperature, humidity,the use of laser technology to measure,very sensitive.
Fine particulate matter,also known as fine particles,fine particles PM2.5.It refers to fine particulate matter in ambient airaerodynamic equivalent diameter less than or equal to 2.5 micron particles.It was suspended for a long time in the air, the higher its content concentration in the air, on behalf of the more serious air pollution.While the Earth's atmospheric composition PM2.5 only a few components in the content,but the air quality and visibility has important impact.Compared with coarse atmospheric particulate matter,PM2.5 particle size is small,a large area, active,easy incidental toxic and hazardous substances (such as heavy metals,microorganisms etc.),and long residence time in the atmosphere,transmission distance,thus a greater impact on human health and environmental quality of the atmosphere.
