Laser Dust Particle Counting Sensor KGD - PM - 202
Product Introduction
The KGD - PM - 202 laser dust particle counting sensor is based on the principle of optical scattering. It can accurately detect and calculate the number of suspended particles with different particle sizes in the air per unit volume. It can simultaneously output the particle numbers of six channels: 0.3μm, 0.5μm, 1.0μm, 2.5μm, 5.0μm, and 10μm. Its performance meets the standards of the JJF1190 - 2008 Calibration Specification for Dust Particle Counters.
