Shanghai Yidian Physical Optics WJL-612 Dry Laser Particle Size Analyzer

Shanghai Yidian Physical Optics WJL-612 Dry Laser Particle Size Analyzer

Laser particle size analyzer is suitable for particle size measurement and analysis of various powders, suspensions, and emulsions, and has been widely used in universities, research departments, and enterprises. The WJL series laser particle size analyzer adopts the full range Mie scattering theory and is designed to comply with the international technical standard ISO-13320. It draws on advanced experience in particle size testing from countries such as the United Kingdom, the United States, and Germany, and its technical indicators are at a relatively high level in China. The WJL series laser particle size analyzer adopts the full range Mie scattering theory, fully considering the optical properties such as refractive index of the measured particles and dispersed media. Based on the changes in scattering intensity of particles of different sizes at various angles, the particle size distribution data of the particle group is reconstructed. The WJL series laser particle size analyzer has multiple models for users to choose from, including dry, wet, and wet dry dual-use models.

The WJL series laser particle size analyzer uses a He Ne gas laser light source with a wavelength of 0.6328 microns, short wavelength, narrow linewidth, good stability, and a service life of over 25000 hours, which can provide stable laser source signals for the system.

The photoelectric detection system has a unique design and high sensitivity, with one main detector and multiple auxiliary detectors arranged in a non-uniform cross three-dimensional fan-shaped matrix. The maximum detection angle reaches 135 degrees, fully ensuring the comprehensiveness of signal detection. The optical path adopts a range design, and the converging light path is unique, reducing the Fourier lens group, making the measurement range wider, the resolution higher, and the optical path adjustable. The ultrasonic dispersion system of the WJL series laser particle size analyzer can fully disperse the tested sample. Even particles with strong agglomeration can be fully dispersed to obtain accurate particle size distribution data. The PADMAS Particle Diameter Measure&Analysis System has powerful functions,

The test data can be processed through averaging, statistics, comparison, and pattern transformation, and has various formats such as differential distribution, cumulative distribution, standard grading, R-R distribution, custom grading, item grading, and quantity distribution. The default grading is 130 levels within the range of 0.02~2000 microns, and the grading can be customized within the range of 1~130 levels.

The test report includes particle size distribution graphs and particle size data charts, as well as characteristic parameters such as D10, D50, D90, average particle size, and specific surface area. There are four custom parameters that can be entered as needed, and weight specific surface area and volume specific surface area can be interchanged. Granular data can be saved to EXCEL.

Supports printing test reports in both Chinese and English formats. The header and footer can be modified as needed, and there is a print preview function. It can save granularity distribution graphics and granularity data charts in image or PDF format for interactive use with WORD. Other processing functions can be added according to user needs.

The fully automatic laser particle size analyzer is an intelligent laser particle size analyzer, which automatically completes all operations under computer control and has special functions such as automatic water inlet, automatic bubble elimination, automatic testing, automatic drainage, automatic saving, and automatic printing. In short, as long as the sample is added to the circulation pool and clicked with the mouse, all operations are completed by the computer, and its comprehensive performance can reach the advanced level of similar products at home and abroad. Specially suitable for laboratory selection in higher education institutions, research institutes, and large enterprises.
