DPC100
Online particle counter monitoring device adopts Laser scattering technology, with a pump-suction sampling method, can accurately detect and calculate the number of suspended particles with different particle sizes in the air. The sensor can simultaneously outputs particle numbers in 6 channels including 0.3μm, 0.5μm,1.0μm, 2.5μm,5.0μm and 10μm.Multiple output options: pcs/m3 (default), pcs/L, pcs/28.3L.
When sampled particles pass through light beam (laser), there will be light scattering phenomenon. Scattered light will be converted into electrical signal (pulse) via photoelectric transformer. The bigger particles will obtain stronger pulse signal (peak value). Through peak value and pulse value quantity concentration of particles in each size can be calculate. Thus, real-time measurement data is obtained through measuring quantity and strength of scattered light
