particle size analysis analyzer / benchtop / automatic / laser

PSA2000ZD is a user-friendly automatic laser particle size analyzer, another breakthrough of our laser particle size analyzers. The measurement range is 0.1-300um. The size distribution is determined by measuring the intensity of the scattered light as a function of the scattering angles, and the theoretical base of calculating is the Mie light scattering. It combines together a patented technique of Fourier transform of converging light, and unconstrained data fitting program and intelligent measurements. Main Features: Principle: Particles of different sizes scatters the illuminating laser into different patterns. In this instrument He-Ne laser is used to illuminate and a photon detector array measures the scattered laser. Software automatically converts the patterns into size distributions. Novel technique: It uses the Fourier transforming of converging laser to reduce the dimension of the instrument, and to obtain precise information of the scattering patterns, particularly the intensity of the scattered laser at very large scattering angles. By simply changing the focal length rather than change a lens, such an optical system can easily adjust its measurement range to measure your specific samples.
