Laser Particle Size Analyzer

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.

Automatic centering system: Keeps the instrument in optimal condition.

Fast sampling speed: Large amounts of data effectively reduce the impact of a few abnormal data on repeatability.

Random function recognition technology and high-speed pre-amplification technology: Maintains stable instrument signals.

Strict calibration with standard samples before leaving the factory: Ensures accurate and reliable test results.

Unique negative pressure detection technology: Prevents lens contamination.


Additional Features and Functions of BGD 251 All-in-One Laser Particle Size Analyzer:

 Positive and negative Fourier patented optical path technology + inclined sample cell technology: Enhances measurement range and improves the accuracy and resolution of fine particle measurement.

Advanced dry sample dispersion system: Sample feeding, air intake, pressure testing, concentration testing, and sample collection are all controlled by a computer, ensuring test stability.

Refractive index measurement function.

PQ verification and data diagnostic functions.

Intelligent dual water level system: Multiple safeguards ensure reliable operation of the instrument.
