Prana Air PM2.5 laser sensor is an industrial grade laser digital PM2.5 sensor. Built in laser and photoelectric receiving module, the principle of light scattering is adopted. The scattered light generated by laser on particles is transtormed from photoelectric receiving device to electrical signal, and then PM2.5 mass concentration and PM10 mass concentration are calculated by specific algorithm.
