Product Description
airborne particle counter (hereinafter referred to as the instrument) is an instrument used to measure the size and number of large dust particles suspended in the air per unit volume.
The instrument adopts semiconductor laser light source, touch computer display, high detection accuracy, simple and clear function operation, computer control, can store and print the test results, and the test environment is very convenient. Widely used in electronics, optics, chemistry, food, cosmetics, medicine and health, biological products, aerospace and other departments.
This instrument uses the principle of light scattering to detect particle size and quantity to detect suspended particle dust.
The air is sucked into the photosensitive area of the suspended particle sensor through the sampling pump for detection, and the dust particles scatter a luminous flux proportional to their particle size.
working principle
Particles in the air will scatter when illuminated by light, a phenomenon called light scattering. Light scattering is related to factors such as particle size, wavelength of light wave, particle refractive index, and light absorption characteristics of particles. But in terms of scattered light intensity and particle size, the dust particle counter has a basic law, that is, the intensity of scattered light by particles increases as the surface area of the particles increases. In this way, the size of the particles can be inferred only by measuring the intensity of the scattered light, which is the basic principle of the light scattering particle counter.
