Product Details：
The RT-1076B is a dry laser particle size analyzer designed for measuring the particle size distribution of powders and granular materials. Using dry dispersion and laser-based particle measurement, it provides fast and repeatable analysis for laboratory testing, quality control, and powder characterization.
Dry Particle Size Analysis for Powders and Granules
Particle size distribution is an important property when evaluating the performance, processing behavior, and quality of powdered and granular materials. The RT-1076B uses a dry dispersion method to separate particles before measurement, making it suitable for materials that can be dispersed effectively in an air stream.
The analyzer is designed for routine laboratory analysis where fast testing, repeatability, and consistent particle size data are important.
Key Features
- Dry dispersion: Designed for particle size analysis of dry powders and granular materials.
- Laser-based measurement: Uses laser optical measurement for particle size distribution analysis.
- Fast testing: Suitable for rapid laboratory particle size measurements.
- High-pressure air dispersion: Helps disperse powder samples before measurement.
- Wide measurement capability: Available configurations support particle size analysis across a broad measurement range.
- Reliable repeatability: Designed for consistent results in routine quality control and laboratory testing.
- Computerized analysis: Measurement data can be processed and analyzed through the control system.
Dry Laser Particle Size Analysis
The RT-1076B is designed for dry laser particle size analysis of powders and granular materials. During testing, the sample is dispersed through a controlled air stream to separate particles before they enter the laser measurement zone. The optical system detects particle scattering and processes the measurement data to determine particle size distribution. This dry measurement method is suitable for routine laboratory testing, material characterization, and quality control applications where fast and repeatable particle size analysis is required.
How the Dry Laser Particle Size Analyzer Works
The RT-1076B uses a laser optical measurement system to determine particle size distribution. The sample is introduced into the dry dispersion system, where an air stream disperses the particles before they pass through the laser measurement zone.
The optical system detects the scattering behavior of the particles. The measurement data is then processed by the computer system to generate particle size distribution results.
Typical Applications
The RT-1076B is part of our powder testing equipment range and is designed for laboratory particle size analysis of dry powders and granular materials. The RT-1076B can be used for particle size analysis of a wide range of dry powders and granular materials, including:

For powder flowability evaluation, our Angle of Repose Tester (RT-730D) can be used to assess the flow characteristics of powders and granular materials.
Why Particle Size Distribution Matters
Particle size distribution can affect powder flowability, mixing, dispersion, packing behavior, processing performance, and final product quality. A reliable particle size analyzer helps laboratories and manufacturers monitor these characteristics and maintain consistent material specifications.
