LLPA-C11 Laser Particle Size Analyzer




Laser Particle Size Analyzer LLPA-C11 is an automatic, benchtop unit with compact design.
It performs both wet and dry dispersion measurements.
It is based on Mie and Fourier (Fourier and inverse Fourier) optical system, scattering theory with ‘Laser Light diffraction technology’.
It offers 0.02 to 2600 μm (Wet dispersion mode) and 0.1 to 2600 μm (Dry dispersion mode) measurement range. Analysis is made easy by incorporating highly advanced automatic SOP (standard operating procedure), to deliver reliable measurement performance, fast and accurate results.
