Best Quality Pm2.5 Laser Sensor Air Quality Detector
Is the air you breathe really clean? Is the blue sky and white clouds you see really clean? Sometimes the sky that seems to be clear may not be really clean, and the air contains many harmful substances. In addition to sulfur dioxide and nitrogen oxides, PM 2.5 cannot be ignored. It has small particle size, large area, strong activity, and is easy to carry toxic and harmful substances. In addition, the residence time in the atmosphere is long, and the transportation distance is long, which affects human health.
PM2.5 is aerodynamic particulate matter with a diameter of less than 2.5 microns, also known as fine particulate matter. Most of the harmful elements and compounds are enriched in fine particles, and as their particle size decreases, the retention time of fine particles in the atmosphere and the absorption rate in the respiratory system also increase, so the impact on human health also bigger.
The birth of PM2.5 detector solves the problem of not being able to know the air quality around you all the time. This is a PM 2.5 detector that can be put in your pocket and can be carried with you wherever you go. Minimalist design, the equipped battery can work continuously for 4~6 hours, the addition of high-precision laser sensor can grasp the PM2.5 value of your environment at any time, so that you can exercise outdoors or work indoors.You can know the surrounding air quality in real time.
