opticallaserfor quality control

Overview
Winner319A is a bench-top split-type laser particle size analyzer designed for spray and aerosol droplet measurement. It applies the Fraunhofer diffraction principle with a parallel light-path layout and an LD pump laser (λ = 532 nm, >40 mW) with a rated lifetime >25000 hours. The instrument is intended for research institutes, university laboratories, corporate R&D centres and quality testing facilities.

Software Functions

• Analysis modes: free distribution, R‑R distribution, log‑normal and category-based statistical models.
• Statistical comparison: compare multiple runs across batches, pre/post processing or different process times.
• Data processing: intelligent statistical processing to generate representative results.
• Custom analysis: define any characteristic particle size between D1 and D100, cumulative percentages for ranges and industry-specific outputs.
• Output: particle size metrics, interval (differential) and cumulative (integral) distributions with graphs (histogram or curve).
• Report export: Word, Excel, image (BMP), text (TXT) and PDF formats.
• One-click operation: automated wet and dry workflows (wet: water intake, bubble removal, dispersion, test, clean, data processing; dry: dust collection, air supply, feeding, test, data processing).
• Interface languages: Chinese and English; additional languages available on request.
• GMP: optional.

Advantages

• Patented optical technologies (parallel optical testing, spectral amplification, auxiliary integration detectors) extend dynamic range and improve measurement accuracy by collecting scattered light across angles.
• Airflow protection device prevents lens contamination during spray tests.
• Split-type design with adjustable test area enables non-contact, non-intrusive measurements across varied spray conditions.
• Stable automatic optical-path alignment simplifies setup and preserves measurement stability.
• Multiple size-distribution models with flexible conversions between volume and number distributions.

Application
Applicable to fire‑fighting sprays, forestry and pesticide spray evaluation, medical nebulizer droplet testing, aircraft engine spray studies, spray prilling and coating, nozzle research, aerosol particle size testing, and laboratories in enterprises, universities and research institutes.
