The Bettersize 2000LD is an advanced, dual-mode particle size analyzer designed for high precision and reliability. It combines both wet and dry dispersion methods to ensure accurate measurement of a wide range of powders. The dry dispersing system uses the Venturi effect to achieve complete powder dispersion through shear, inertia, and collision forces. This instrument stands out for its high accuracy, excellent repeatability, user-friendly operation, fast testing speed, and broad measurement range. It integrates dual-lens technology and intelligent testing features, making it ideal for large enterprises, universities, research institutes, and key laboratories.

Excellent Repeatability
Why does the Bettersize 2000LD offer such good repeatability? The instrument is equipped with a stable and efficient dispersion system. It also features a reliable laser source, detector, and signal transmission system. An automatic alignment mechanism ensures that the device remains in optimal condition at all times. With a sampling rate of up to 3,500 times per second, the system can effectively minimize the impact of any abnormal data on measurement consistency. High-precision lens groups provide clear imaging and low distortion, ensuring that scattered light from all angles is fully captured. 
Tip: Repeatability is one of the most important performance indicators for a particle size analyzer. If repeatability is poor, the instrument loses its value. Factors like the equipment, operator, voltage, water quality, and environmental interference can all affect repeatability. It’s a comprehensive reflection of multiple variables.
High Accuracy
What makes the Bettersize 2000LD so accurate? It features a dual-lens optical system developed by Bettersize. The use of high-quality composite lenses significantly improves measurement accuracy. The system includes 84 photodetectors, combined with advanced software, enabling precise automated testing even for complex samples with single, double, or multi-peaks. A complete sample preparation system includes circulation, ultrasonic dispersion, stirring, and automatic water supply. Testing results have been verified using standard samples, and the outcomes match the expected values.
Consistent with overseas advanced laser particle size analyzers.
