Laser Particle Counting Sensor KGD - PM - 203
Product Introduction
The KGD - PM - 203 laser 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 (pcs/L) of six channels: 0.3μm, 0.5μm, 1.0μm, 2.5μm, 5.0μm, and 10μm, and its counting efficiency meets the calibration standard specifications of the JJF 1190 - 2008 for dust particle counters.
