Product Details
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.
