Laser particle size analyzer PA-1155LW

laser light scatteringlaser diffractionfor the food industry

Description
PA-1155LW is an automatic laser particle size analyzer designed for wet dispersion measurements. The instrument integrates computer-controlled optical alignment, zero calibration and fully automated sample handling including ultrasonic dispersion, mechanical stirring, cyclic sampling to the detection zone and automatic cleaning. Typical analysis time is under 2 minutes per sample and results are recorded, stored and printable via the software.

Application range
Molybdenum, magnesium, zinc, aluminium powders; lithium carbonate, strontium carbonate; white carbon black, wollastonite, bentonite, zirconium silicate; calcium carbonate, talc, kaolin; coatings, cement, food, pesticides, rare earths, catalysts, foaming agents, mica, abrasives, fillers, graphite, pigments, pharmaceuticals, chemicals, electronics, papermaking, metallurgy, ceramics and other industries for solid powders or emulsions particle size distribution testing.

Instrument Features

• Fully integrated system: optics, electronics, sample cell, ultrasonic disperser, mechanical stirrer, circulation and automatic cleaning under computer control.
• Built-in ultrasonic disperser and mechanical stirrer minimize residence time in tubing, reducing re-agglomeration and improving repeatability and stability comparable to international instruments.
• Compact integrated design combining measurement unit and sampling system for simplified use and maintenance; electrical anti-interference design increases operational reliability.
• Serial data transmission enables easy connection to laptops and desktops for a complete particle size testing system.
• Software available in English and Chinese with a user-friendly interface. The automated workflow (parameter selection, centering, background, concentration adjustment, signal acquisition, analysis, reporting and cleaning) runs after pressing the "Auto Test" command.
• Reports include cumulative and interval particle size distributions, histograms and key metrics such as D10, D50, D90, D97 and mean particle size.
• Preset optimal test modes allow storing parameters (refractive index, distribution mode, concentration, ultrasonic time, sampling time, cycle rate, cleaning time) for reproducible results.
• Rugged design: shockproof, dustproof and moistureproof for transport and operation in demanding environments.
