Online Dust Particle Counter OPC-203 with 0.3-10μm Particle Size Range, 50%@0.3μm Counting Efficiency, and RS485 Communication Interface
Online Dust Particle Counter KGD - OPC - 203
Product Introduction
The online dust particle counter KGD-OPC-203 adopts the principle of optical scattering, which 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 the unique intelligent dust source identification module of KACISE, and is equipped with an air pump with a stable flow rate. It can simultaneously output the particle numbers of six channels, namely 0.3μm, 0.5μm, 1.0μm, 2.5μm, 5.0μm and 10μm (the default unit is pcs/m³, and it can be switched to pcs/L or pcs/ft³). The indication error meets the JJF 1190 standard.
Product Features
