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 .
