Fiber-Optics Particle Analyzer with Auto-sampler  FPAR-1000AS

Automatic particle size measurement system with an auto-sampler for a maximum of 50 samples using disposable cell (sample qty. 1ml)


  • Supports automated continuous measurement of up to 50 samples with the auto-sampler.
  • Supports high-speed and high-precision measurement of particle size and particle-size distribution in a wide concentration range from diluted to concentrated solutions.
  • Provides monitor functions for dispersion and cohesion processes which is unique to micro particles, and can be used for a wide range of purposes in research and quality control.
  • The newly developed measurement probe supports high precision particle-size measurement in concentrated solutions.
  • Compactly designed in A3 size with all necessary functions built in including sample heating control and ultrasonic cleaning.
