Tips: What is the working principle of laser particle counter?
A laser particle counter is an instrument that uses the principle of light scattering to count dust particles. Light scattering is related to factors such as particle size, light wavelength, particle refractive index, and particle absorption characteristics of light. However, in terms of the intensity of scattered light and the size of particles, there is a basic rule that the intensity of light scattered by particles increases with the increase of the surface area of the particles. In this way, a certain flow of dust-laden gas passes through a beam of strong light, causing the particles to emit scattered light, which is projected onto the photomultiplier tube through the condenser lens, and the light pulse is converted into an electric pulse, and the number of particles is obtained from the number of pulses. The particle diameter is obtained from the function relationship between the intensity of the particle scattered light and the particle diameter.
