Laser Particle Size Analyzer, Professional PSA-2L2309A

PSA-2L2309A is an intelligent fully automatic laser particle size analyzer that adopts the internationally advanced Mie Scattering and Fraunhofer Diffraction principle. As an integrated model with wet and dry dispersion systems, it features a high-sensitivity and high-resolution photoelectric probe system paired with an imported Canon lens optical path—these components ensure excellent accuracy and repeatability in particle size distribution measurements. The analyzer is widely used in quality control departments of industrial production and research institutions.

Features

Unique Separated Modules for Wet and Dry Dispersion

The instrument employs a modular design for automatic dry and wet dispersion. Users can freely assemble the modules according to the testing requirements of sample characteristics, making the operation simple, convenient, and efficient.

Flexible Operation Modes

Both an intelligent fully automatic operation system and a manual operation mode are available for free selection. The automatic mode is extremely easy to learn and supports SOP operation, streamlining the testing workflow.

Advanced Optical Path Design

Adopting inverse Fourier (folded optical path) technology, the reception of scattered light from sample particles is not limited by the focal length of the optical path. The test angle range spans 0.015° to 145°, effectively expanding the measurement range and improving the instrument’s resolution. The sealed optical path also delivers excellent dustproof performance.

Automatic Optical Path Alignment System

Composed of precision four-phase hybrid stepper motors with a micro-stepping precision of micron level, this system maintains the optical path in an optimal state at all times, ensuring accurate and stable test results. It eliminates the need for manual optical path adjustment, reducing human intervention errors.

Automatic Sample Dispersion System

The modular design of the wet and dry dispersion systems shortens the circulation pipeline, preventing the sedimentation of large particles. This design not only facilitates uniform sample dispersion but also lowers maintenance costs and simplifies equipment cleaning and upkeep.

High-Performance Instrument Software

The proprietary unconstrained free fitting technology collects scattering data in real time during the measurement process and can automatically analyze multi-modal particle groups without being restricted by fixed functional models. Analysis results depend entirely on the distribution of the scattering spectrum, maximizing fitting accuracy and truly reflecting the particle size distribution of samples. For particles below 2 μm, the analyzer performs testing across 12 particle size grades with ultra-high physical resolution.
