Particle counter is a principle of light scattering particle counting instruments. Lightscattering particle size, and the wavelength and particle index of refraction and particulate light absorption characteristics and other factors. Scattered light intensityand particle size, however, there is a basic rule, that is, particle scattering light intensity increased with the increase in the surface area of the particles. The dust concentration in the gas must flow through a beam of intense light, particles scatter light, projected on the photomultiplier tube through the condenser lens, the light pulses into electrical impulses, by the number of pulse particles is obtained. According to particle scattering light intensity and size function of particle diameter is obtained. As long as determination of the intensity of scattered light shows the particlesize, is the basic principle of light scattering particle counter.
