Fine particulate matter is also called fine particulate matter, PM2.5. Fine particulate matter refers to the particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 microns. It can be suspended in the air for a longer time. The higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small part of the earth’s atmosphere. But it has an important impact on air quality and visibility. Compared with coarser atmospheric particulate matter. PM2.5 has small particle size, large area, strong activity, easy to carry toxic and harmful substances (such as heavy metals, microorganisms, etc.), long residence time in the atmosphere and long-distance transportation. Therefore, it has a greater impact on human health and the quality of the atmospheric environment. Air particulate meter can monitor these fine particulate matter.
Introduction of PM2.5 sensor
Jingxun Changtong independently developed an air particulate meter. The product uses a laser probe for professional testing of PM2.5/10 concentration sensors as the core detector. It has a wide measuring range, high precision and good linearity. Good versatility, easy to use, easy to install. Long transmission distance, moderate price and medium characteristics. The system uses pump-suction probes. Air is pumped into the sensor by a fan. Compared with ordinary diffusion sensors, it has better response speed and higher accuracy.
air particulate meter applications
It can be used in equipment such as air purifiers, air quality detectors, air conditioners with air purification functions, automobiles and consumer electronics. Aiming at the dust and haze in the air. Dust particles in the air will follow the breath and enter the human respiratory tract, which is very harmful to human health. The higher the concentration of PM2.5 in the air, the more serious the air pollution. Intelligently filter PM2.5 particles in the air. It can be customized for secondary development, which can better meet your diversified needs.
