Dry wet laser particle size analyzer

Laser particle size analyzer

1： Product principle

HL2020-CDry wet dual-use laser particle size analyzerAdopting the internationally recognized Mie scattering principle. The high-density detector and seamless full-scale testing method ensure the accuracy and repeatability of the test results. Its wet circulation dispersion system ensures no particle deposition during particle testing and no accumulation of waste liquid after drainage, ensuring the accuracy of the second test and making the test results more authentic and reliable; The dry dispersion method adopts a linear jet dispersion method, where the sample is dispersed by high-pressure gas and flies vertically backwards to avoid secondary clustering of the tested particles. At the same time, a pipeline residue free design is adopted to ensure the accuracy of testing different samples. The HL2020-C's advantages are highlighted by its carefully designed optical path automatic calibration system, dry wet one key switching system, and dry computer remote control feeding system.
