Colorlight LED display accessories SSR-PM air quality (PM2.5/PM10) transmitter

Description Colorlight SSR-PM Air quality (PM2.5/PM10) Transmitter SSR-PM is an industrial transmitter universal particle concentration, measured using laser light scattering principle, the unique data acquisition technology dual sieved particles obtained number of particles per unit volume equivalent particle diameter, and a unique scientific the algorithm calculates the concentration of particulate matter per unit volume equivalent particle diameter, and is output via data interface 485 ModBus-RTU protocol. It can be used for monitoring the concentration of PM10 or PM2.5 need a place outdoor weather, dust monitoring, libraries, archives, and other industrial plants. Range: 0-6000ug/m3, the resolution: 1ug/m3; PM2.5, PM10 simultaneous output; Unique dual automatic data acquisition and calibration techniques, consistency of up to ±10%; The use of advanced laser anti-attenuation technology to ensure long-term stability of equipment; ModBus-RTU standard communication protocol, easy access; Standard wire length: 5 meter.
