Laser Particle Size Analyzer
The laser particle size analyzer utilizes the scattering phenomenon of particles to light, deducing the particle size distribution of the measured particles based on the distribution of scattered light energy. By integrating and optimizing optical, mechanical, electronic, and computer systems, this instrument achieves rapid and accurate measurement of particle size distribution in solid powders or emulsions. It can output the particle size distribution table, distribution curve, average particle size, median diameter, specific surface area, etc., through supporting software. It features intuitiveness, good repeatability, a wide dynamic range, and simple and convenient operation.
Characteristics:
◆ Automatic testing technology: One-button operation, simple and convenient.
◆ High-performancelaser: Stable output, good monochromaticity, high efficiency, significantly improving measurement accuracy.
◆ High-performance stable detectors: Up to 80 (BGD 250) or 92 (BGD 251).
◆ High-performance software: Accurate testing for samples with single, double, or multiple peaks.
◆ Comprehensive sample preparation system: Includes automatic circulation, ultrasonic dispersion, stirring, automatic water intake, automatic cleaning, and dry burn prevention, suitable for all samples, ensuring full dispersion and accuracy and repeatability of test results.
