Principle
The instrument adopts the principle of light scattering, which is sensed by the detection laser of the laser Optical inspection Sensor, and the light scattering intensity is proportional to its particle size. When the suspended particles in the air pass through the photosensitive area, the scattered light is accepted by the photosensitive element and generates a pulse signal. After photoelectric conversion, amplification and processing, the equivalent diameter and quantity of the collected particles are obtained, so as to detect the size and quantity of dust particles.
Applications
Electronics industry, pharmaceutical industry, semiconductor industry, Optical inspection, precision machining field, food manufacturing, cosmetics manufacturing, biological products, hospitals, environmental protection, inspection, aerospace and other industries production enterprises and scientific research departments, as well as epidemic prevention stations, disease control centers, blood centers, mass supervision institutions and other institutions
