Applications
dusty material, suspending liquid, two phase current material pellet grain-size distribution. the like titanium oxide powder, the bead burnishing powder, the grinding compound, plants the clothes medicinal preparation, the fat breast, the organosilicon and so on.

Theory principle
The broad angle laser scattering technology is the technology which the angle light scattering technology expands since childhood, started from the 1960s to serve as the laboratory granularity measuring technique, but the broad angle laser scattering technology could survey the particle size was smaller.
Sizing test based on by pellet scattering coherent bundle intensity distributed observed value. When laser beam and pellet interaction, has the grain-size distribution to be possible to calculate based on the diffused light distribution, the scattering design observes the Mie scattering theory.
The aqueous method survey is refers to the sample disperses to the liquid resolver, through a thin transparent sample pond, so that the laser can penetrate. The dry process disperses complex many, needs to disperse the sample in the air current, then collection, and the safeguard does not pollute the instrument internal optical device.
The light's scattering three-dimensional model like figure to the right shows. path of rays model The pellet shows on detector scattering design following chart, it is the massive pellets the smooth surface which forms in the different angle, in this surface has contained the particle size distributed detailed information, by scattering design which obtains, applies the Mie laser scattering principle and the shape refractive index adjustment model, then calculates the granularity the distribution.
FINESIZER 5000 use the most superior matrix arrangement, thus analyzes the pellet group comprehensively the grain-size distribution.
Compares with the big pellet, the finely ground particles scattering distribution is more scattered, the three-dimensional scattering matrix can the very good gathering scattering luminous intensity, produce the signal uses for to calculate the grain-size distribution. Some light beam power detector does not examine the diffraction laser beam, with the aim of carrying on the sample degree of dilution control. The figure above is the FINESIZER 5000 path of rays charts.

Wet/Dry method with ease changes
The modular design's dry process unit, is advantageous for the fast replacement and clean. The dry process control unit is put in the machine crown to save the space, the getter device uses the drawer type pattern, is advantageous for the replacement. When replacement aqueous method pattern only need change into the dry process getter device the aqueous method the sample pond installment, is then convenient. Specimen handling speed digital adjustable, the granule carries on the dispersion before the path of rays through 3 level of adjustable compressed air, the getter device can guarantee that the greatest degree the collection pellet dust, avoids polluting the path of rays system.

The control panel control dispersion circulates
The built-in agitation unit and the supersonic dispersion unit, the agitation speed and the supersonic operating time may the digit adjustable. Can enable the great proportion pellet, the reunion pellet to obtain the full dispersion. The power zoom type circulating pump can carry disperses the good pellet group to pass the path of rays.

The sample window, with ease cleanly replaces The drawer type module design
facilitates the disassemblage clean, facilitates the installment. The sample window quartz plate may disassemble, even if has the dirt to pile up may also disassemble cleaning in the sample window to be clean.

Reported that the pattern may choose
Many kinds of report patterns may elect, the data may relaxed and EXCEL and ORIGIN is interactive

High keen optical sensor
Photorectifier three-dimensional matrix pattern arrangement, most superior pattern development pellet group luminous intensity distribution characteristic. Supplementary optics density detecting element, real time display sample density. The unique path of rays structure, has guaranteed the high precise survey. USB connection The USB connection convenience with the notebook and so on portable installment connection, the relative serial port transmission speed is quicker, real-time.
