Particle counters from the development of the microscope, experienced a microscope, sedimentation tube, sedimentometer, centrifugal sedimentometer, particle counters, laser air particle counters, PCS nano-laser air particle counters, which due to the laser air particle counters test speed, dynamic distribution of the wide range of human influence and other aspects of the advantages of the counter and become the mainstream products in many industries.
CW-HCC600 six-channel handheld dust particle counter basic principlesAir particles in the light of the irradiation will occur under the scattering, this phenomenon is called light scattering. Light scattering and particle size, light wavelength, particle refractive index and particle absorption characteristics of light and other factors. But on the scattered light intensity and particle size, there is a basic law, that is, the intensity of the scattered light particles with the increase in the surface area of the particles and increase. Thus, as long as the measurement of the intensity of scattered light can be deduced from the size of the particles, is the basic principle of the light scattering particle counter. In fact, each particle produced by the scattered light intensity is very weak, is a very small light pulse, the need for amplification through the photoelectric converter, the light pulse into a larger signal amplitude of the electrical pulse, and then further amplification and screening through the electronic circuit to complete the counting of a large number of electrical pulses. At this time, the number of electric pulses corresponds to the number of particles, and the amplitude of electric pulses corresponds to the size of particles.
The specific working principle of the dust particle counter: the light from the light source is focused by the lens group in the measurement chamber, when each particle in the air quickly through the measurement chamber, it will be the incident light scattered once, forming a light pulse signal. This light signal is sent to the light detector through the lens group 2, and is converted into an electrical pulse signal proportionally, and then amplified and screened by the electronic circuit of the instrument, picking out the required signal and displaying it through the counting system. It should be noted that, although the instrument is called "counter", but the ability of the instrument to distinguish the size of the particles is more important. The counting of electrical impulses is simple, but the judgment of the size of the particles is very important.
