Laser diffraction particle size analyzer PA-3000SL

opticallaserlaboratory

Product description
PA-3000SL is a split-type spray laser particle size analyzer based on full-range Mie scattering theory and proprietary algorithms. The instrument features a fully sealed metal enclosure with electromagnetic shielding for stable, low-interference operation. It performs rapid sampling of droplets to deliver fast, representative particle size data for sprays, aerosols and mists.

Application area
Designed for measurement of droplet/particle size in nozzle manufacturing, medical spray systems, spray drying, fire-fighting nozzles, aerosol production, environmental monitoring (smog, smoke) and research laboratories.

Granularity test report shows
The software user interface supports English and Chinese. Available report formats include cumulative distribution, normal distribution and RR distribution. Reports provide cumulative and interval particle size distributions and curves, histograms, characteristic diameters (D3, D10, D25, D50, D75, D84, D90, D97), volume-mean and area-mean diameters, specific surface area and related statistics.

Practical case of spray laser particle size analyzer

Instrument advantages

• Main and auxiliary units can be separated up to 10 m to adapt to site conditions; the nozzle (provided by user) connects to the gas supply and the sample is placed between units. The auxiliary unit moves laterally for optimal positioning and the controller automates liquid/gas feed.
• Proprietary algorithm reduces influence of spray and position changes on results; laser power is fully adjustable to accommodate very low to very high concentrations.
• Standard particle board supplied for on-site calibration and verification.
• Continuous automatic testing with reports generated as fast as once per second; supports continuous recording and statistical comparison of multiple measurements.
• All-metal chassis and robust mechanical design provide strong electromagnetic shielding, vibration resistance and optical stability.
