Cement Wet Laser Particle Size Analyzers

Order Id: PSA2000S
Categories: Particle Size Analyzers 



The PSA2000S is a laser particle size analyzer designed for cement industries. It combines the Mie light scattering principle, a patented technique of Fourier transformation of converging light and an unconstrained fitting program, to ensure the reliability and reproducibility of the measurement results. Dehydrate ethanol is used as dispersing medium and is recyclable. The results execute the standard ‘China’s cement particle measurement, laser diffraction method’ in the building material industry.

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.
 Built-in dispersing system: We carefully aligned the stirring set-up, the ultrasonic dispersing unit and the sample circulation pipes, and fixed them inside the instrument. Such a built-in design effectively prevents the inhomogeneous dispersion and sedimentation of big particles, which can be observed in the designs that these dispersing units are separated from the instruments, where the sample circulation pipes are therefore too long.
Unconstrained data fitting program: the particle analysis software uses a unique unconstrained data fitting technique that we developed to intelligently measure an unknown size distribution, this is particularly important for material researchers, or for measuring particle size distributions with multiple peaks in data.
 Micro sample chamber: The capacity of the micro sample chamber is as small as only 10ml. This helps with measuring expensive/precious samples, or samples difficult to be dispersed within medium.
Rich software functions: Beside the basic function of analyzing the size distributions, the software also has the following features:
 The output has rich content including: size distribution, R-R distribution, logarithmic distribution, statistics within different size ranges, volume distribution, number distribution, the percentage of particles of a certain size, or a certain size range, and comparison of multiple results.
 The output could be in Word, Excel, Bmp pictures and Text formats, and this makes easy viewing and referencing the results at different situations.
 It supports English and Chinese languages, and it can be changed to many other language versions according to the user’s needs.
 Calibration: Throughout the measurable size ranges the instrument is calibrated with the standard reference particulate materials used in abrasive industry. The accuracy execute JIS Japanese standards or FEPA European standards
