Laser PM2.5 monitor, and infrared PM2.5 monitor; Laser characteristics: it can measure 0.5 micron, some of which have been able to measure 0.3 micron particles, using the principle of counting measurement, so the measurement accuracy is relatively high. Infrared is based on photometric principle, and can measure particles about 1 micron in size. Laser PM2.5 monitor is a good quality measuring instrument for household use at present, and it is also the main direction of development. The price of laser PM2.5 monitor ranges from more than 500 yuan to 1000 yuan or even over 10, 000. Household use is often 500 to 1000, depending on the quality of course. Generally speaking, the data of laser PM2.5 monitor is more credible.
The hand-held
PM2.5 monitor is a hand-held battery-powered light scattering laser photometer with data recording function, which can provide users with a large number of real-time aerosol readings. It uses sheath gas system to separate aerosols in the optical element chamber, which can keep the optical elements clean, improve the reliability of the
air pollution analyzer and reduce the maintenance rate. It is not only suitable for clean office environment, but also for harsh industrial production areas, building and environmental protection sites and other outdoor applications.
Aerosol monitor can measure aerosol pollutants, such as dust, smoke, harmful smoke and fog. Aerosol concentrations corresponding to PM1, PM2.5, inhalable particulates or PM10 fractions were measured. Light portable structure; manual function and programmable data recording function; single-point data recording function device; the aerosol concentration ranging from 0.001 to 150 mg/m3 can be measured. The advent of the PM2.5 monitor brings convenience for people to use and great benefits to the change of living environment.
