Working Principle:
Multi-angle La0ser Scattering Detection, la0ser irradiation in the suspended particulate matter in the air and generate scattering. Scattered light will be collected in a specified angle at the same time. According to the scattering intensity, time-varying curves can be obtained through the sensor. Being processed by the microcomputer processor, equivalent particle diameters and the number of suspended particulate matter with different sizes in per unit volume can be obtained.
