LS-POP(6) Laser particle size analyzer

 Details

LS-POP (6) is OMEC’s 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. OMEC’s instruments own the advantages of wide measurement range, good repeatability, simple operation and etc. through OMEC’s 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.

Patent

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.
