SEM224 industrial grade general particle concentration transmitter adopts the principle of laser scattering measurement and sieves through unique data dual-frequency acquisition technology to obtain the number of particles of equivalent particle size per unit volume, and uses a scientific and unique algorithm. Calculate the mass concentration of the particles with the equivalent particle size per unit volume, and output the data through the ModBus-RTU protocol with the 485 interface. It can be used in outdoor weather stations, dust monitoring, libraries, archives, industrial plants and other places that require PM2.5 or PM10 concentration monitoring.
