Semi-auto Wet Dispersion Laser Particle Size Analyzer

PA-POP6LW Semi-auto Wet Dispersion Laser Particle Size Analyzer is basic product, the actual measurement range has reached domestic advanced level, it is a cost effective laser particle size analyzer.

Application
measure the particle distribution of the powder and latex

Principle
Using the phenomenon of light scattering of particle, according to the distribution of scattering light energy, to calculate the size distribution of particles measured. Our instruments own the advantages of wide measurement range, good repeatability, simple operation and etc. through our system integration and optimization for optics, mechanics, electronics and computer.

Report Items
Particle size distribution table, particle size distribution curve, average particle size, median diameter, specific surface area, etc.

Features

• Adopt unique scattered light detection around a sphere surface (patent no.:95223756.3), after lens (also known as “reversal” or “converging light”) Fourier transform structure, place large angle detectors on proper spherical surface, to realize the accurate focusing of large angle scattered light.
• Use integrative laser emitter (patent no.: 00228952.0), effectively reduce the thermal deformation of laser tube, the influence of outside mechanical vibration on the stability of the instrument.
• Wet sample feeding system adopts booster pump, top speed can reach 2800 rpm, can effectively realize the circulation of large particles.
• Inlet and outlet water solenoid valve adopts Germany Baode imported products, precision control action, durable.
• Measurement window material uses high quality optical materials, window components adopt full stainless steel material, wear-resisting, easy to clean, and maintenance is convenient.
• Light path system uses fully-enclosed design, preventing dust pollution and outside light pollution.

The Application of Patents and Proprietary Technology

• Scattered light detection around a sphere surface (DAS)
  The large angle detectors are placed in a spherical surface to get accurate focusing of large angle scattered light.
• Integrated laser emitter

The beam expander and the pinhole filter are integrated in several concentric tubes, and then jointed into one tube with both ends enclosed. It is shock proof, easy to maintain and with stable laser output.
