Low Concentration Dust Detector KGD-OPC-211
Low Concentration Dust Detector KGD-OPC-211
Product Introduction
The Low Concentration Dust Detector KGD-OPC-211 adopts the principle of optical scattering. It can accurately detect and calculate the number of suspended particulate matters of different particle sizes in the air per unit volume. It is equipped with KACISE's unique intelligent dust source identification module. With a large gas sampling rate of 6L/min, it can simultaneously output the particle numbers of twelve channels, namely 0.3μm, 0.4μm, 0.5μm, 0.6μm, 0.8μm, 1.0μm, 1.5μm, 2.0μm, 2.5μm, 5.0μm, 8.0μm, and 10μm, as well as the mass concentrations of PM2.5 and PM10. The indication error meets the standard of JJF-1190.
