Main Features:


 1)Wet and dry sample dispersion system Integrated Design

This instrument integrated wet and dry dispersion test in one, successfully resolved the  problem of dry and wet technology integration, realize one key to switch.  


2) Intelligent full automatic operation system and manual operation mode, freely choose.


With intelligent automatic mode of operation, to achieve a key test, as long as according to the prompt addition of sample, click the "test", all process will be complete automatically,

not only reduce the testing workload, but also eliminate the interference of human factors, to further improve the accuracy and authenticity of testing results.

Wet method: A key to complete water-supply, dispersion, circulation, testing, cleaning, data record, data analysis, save and print are automatically completed, only take 2 mins.

Dry method: A key to complete the dust collecting, air supply, feeding, testing, data processing and other operation, take 1 min.



3) Stable and unique optical path system patented technology

Converging light Fourier transform path system, enables scattering light be not restricted to the lens aperture limit, and Dual-laser orthogonal light technology make use of the semiconductor auxiliary laser extend the test angle from 45 degree to 135 degree, ensure receive all the angles of signals.


4) Automatic Optical path alignment System,

The precision of four hybrid stepping motor in the automatic system of optical components, micro precision of 0.1um, the instrument of light path is always at its best to eliminate manually on the light path and the troubles and difficulties but also enhance the accuracy and stability of test results.



5) Full built-in Sample dispersion system.

 Auto wet dispersion system,SOP realize one key operation.

set mechanical stirring, ultrasonic dispersion, and circulation path in one, It ensures particles uniform dispersion and distribution,avoids many bad phenomenon, such as uneven distribution of particles, large particles deposit because of the long outer dispersing system tube,  And it guarantees the representativeness of test result.

For dry dispersion system, Turbulence dispersion patented technology and Normal shock shearing effect, make particles sufficient dispersion,ensure good test.


 6)Instrument Software

Original Unconstrained free fitting patent technology collect scattering data during the measurement process, make particle analysis not be restricted by any functions, truly reflect particles size distribution, The instrument provide high precision data with



4. Software Function:


1, Analysis Mode

Free Distribution, R-R Distribution, Logarithm Normal Distribution, Mesh number classification etc. meet different demands of particle size statistic in different industries.
