working principle
Laser scattering theory : When laser irradiation through the particle detection position will produce a weak scattering of light in a specific direction of the light scattering wave and particle diameter about you can get different grain through the waveform classification statistics and conversion formula different size number concentration of particle diameter in real time in accordance with the calibration methods with the official unit of uniform concentration .
