In the field of powder particle size testing, magnetic materials, lithium carbonate, medicinal powder, cement, chemical, and other powders that are not suitable for water (wet method) testing. To obtain accurate test results, dry method laser particle size meters are generally used for measurement. PA-1178LD dry-type laser particle size analyzer uses a unique device to realize instantaneous dispersion and instantaneous measurement, thereby ensuring the repeatability and stability of the instrument. This instrument has fast test speed, fully automatic operation, and stable results. It is the first choice for testing dry powder particle size distribution in various industries.
Application
Magnetic materials, medicinal powder, cement, powder coatings, chemicals, food, pesticides, electronics, papermaking, metallurgy, ceramics, building materials, abrasives, calcium carbonate, talc, kaolin, alumina, rare earth, catalysts, blowing agents, fillers, graphite , Pigment and other industries of solid powder particle size testing.
Instrument Features
- The unique design of the photodetector array with 92 detectors makes the resolution of the instrument extremely high.
- Direct test of dry powder without dispersant and solvent.
- The test software has a friendly interface and easy operation. You only need to press the “Auto Test” button, and then place samples 4, 4 on the injection site according to the prompts. All measurement processes (including measurement parameter selection, centering, and background) (Measurement, concentration adjustment, signal sampling, data analysis, report generation, etc.) are completed automatically under computer control, and a test report is output. With results storage, query, comparison, editing, deletion and other functions.
- the software is powerful, there are Chinese and English versions for users to choose to use. It has six different report forms such as free distribution, normal distribution, and RR distribution. The content includes cumulative particle size distribution data and curves, interval particle size distribution data and histograms, and typical particle size values such as D3, D10, D25, D50, and D75. , D84, D90, D97, D98 and other data.
- The instrument’s light-mechanical and electrical integration structure is divided into three major components: the main machine, auxiliary equipment (filter separation purifier, dust extraction system, dust storage tank), oil-free mute air compressor, with a fully sealed structure, which effectively prevents dust. Pollution, strong anti-interference ability, the system automatically recycles waste materials.
