  • Laser Particle Size Analyzer - China

    price: 10000.00 Dollar US$

    FDQ-0301 laser particle size analyzer based on physics Fraunhofer diffraction and Mie scattering theory basis. This theory can be simply understood as: travels in straight lines parallel laser beam blocking particles encountered in the communication process, the phenomenon of diffraction and scattering, and small angle light scattering large particles, small particles of light scattering angle is large.
    Figure 1-1 shows the diffraction pattern formed by individual particles, the larger the particle diameter, the smaller the center of the bright ring, the smaller the particle diameter, the larger the center of the bright ring. Use photo detector array receiving light at different angles, for the corresponding angle, its energy is set corresponding to the diameter of the particles occurs diffraction (scattering) caused by the respective other angle light will reflect the strength of the corresponding diameter of the particles throughout the assembly of particles occupies proportion, according to the intensity of the received scattered light at different angles, you can perform anti-particle distribution of the sample between the relative content and various size fractions.
    1. Up to 82 sampling channels to improve the resolution of the test results; all the photovoltaic device fabricated on a single silicon chip, to ensure the life of the photovoltaic array; cross-sector arrangement, increasing the light receiving area, improves the sensitivity ;
    2. micro injection method, using a peristaltic pump automatic loop injection mode, using siphon pump automatic cycle injection mode, to meet different customer test requirements, the instrument comes standard MS-01 micro-injector device;
    3. The single lens full scale measurements, all optical components are mounted on reinforced base before fastening a good optical system is shipped, the instrument more stable performance;
    4. Imported semiconductor lasers, has a long life, stable optical parameters, not afraid of vibration and a series of advantages, continuous working time of up to 24 hours, to meet user requirements for large continuous load test.
    Technical Parameters
    1, the test range (um): 0.15-400; (0.4-1100, 0.1-450, 0.25-650, 0.4-1100)
