Automatic laser particle size analyzer (wet method), 0.1µm～155µm

PA-1155LW laser particle size analyzer is an intelligent laser particle size analyzer. The PA-1155LW laser particle size analyzer was born more than 20 years ago. Since the original manual operation of the touch switch, it is now fully automatic under computer control and the optical path is automatically aligned. Zero calibration, just click a button, the menu prompts to add dry powder or emulsion slurry to the sample cell, automatic stirring, ultrasonic dispersion, circulation to the test area, and the discharge cleaning process is fully automatic. The test speed is extremely fast. Each sample is 2 Completed in minutes, the results are automatically recorded and saved by the computer, easy to view and print.

Application range

Molybdenum powder, magnesium powder, zinc powder, aluminum powder, lithium carbonate, strontium carbonate, white carbon black, wollastonite, bentonite, zirconium silicate, calcium carbonate, talc, kaolin, coating, cement, food, pesticide, rare earth , Catalyst, foaming agent, mica powder, abrasive, filler, graphite, pigment, medicine, chemical industry, electronics, papermaking, metallurgy, ceramics and other industries in solid powder or emulsion particle size distribution test.

Instrument Features

1.        The instrument integrates optics, circuit, sample cell, ultrasonic dispersion, stirring cycle, automatic cleaning and integration, and automatic centering and correction under computer control.
2.        Because the unique ultrasonic disperser, mechanical stirrer, circulation device, etc. are set inside the instrument, the time for the sample to flow in the pipeline is short. It avoids delamination and re-agglomeration after the sample is dispersed, thereby ensuring the repeatability and stability of the instrument, and the accuracy reaches the measurement level of similar foreign instruments.
3.        The instrument adopts advanced molding technology to make the structure of the instrument compact and reasonable, that is, the measurement unit and the sampling system are integrated, the appearance is beautiful and easy to use and maintain; the latest anti-interference technology is used to make the electrical stability of the instrument better. The failure rate is lower.
4.        It adopts serial data transmission mode, which can be easily connected with various laptops and desktop computers to form a granularity testing system, which completely bids farewell to the traditional board connection method.
5.        The software has Chinese and English versions for users to choose and use. The testing software has a friendly interface and easy operation. You only need to press the “Auto Test” button, and then put the measured sample into the instrument sample pool according to the prompts. All measurement processes (including measurement parameter selection, centering, background measurement, and concentration adjustment) , Signal sampling, data analysis, reporting, sampling system cleaning, etc.) completed automatically under computer control, output test report. With results storage, query, comparison, editing, deletion and other functions.
6.        The content of the test report includes cumulative particle size distribution data and curves, interval particle size distribution data and histograms, typical particle size values ​​such as D10, D50, D90, D97, and average particle size.
7.        Optimal test mode can be preset: for various samples, the best test parameters can be set, such as refractive index, particle size distribution mode, concentration, ultrasonic dispersion time, sampling time, cycle rate, cleaning time, etc. Conveniently obtain the most reliable and highly reproducible test results.
8.        The instrument adopts shockproof, dustproof and moistureproof design, which is convenient for transportation and working in harsh environment.
