Overview
The air filtration efficiency monitor adopts the principle of optical scattering, which can accurately detect and calculate the number of suspended particles of different sizes in the air per unit volume. It is equipped with a four sided photoelectric dust source intelligent recognition module and a flow stable air pump. It can simultaneously output the number of particles in six channels: 0.3 μ m, 0.5 μ m, 1.0 μ m, 2.5 μ m, 5.0 μ m, and 10 μ m (default unit: pcs/m m); #179; , switchable pcs/L, pcs/ft3), with indication error meeting JJF 1190 standard.
