Advantages

• Patented unconstrained free‑fitting software analysis for more accurate particle size distribution representation.
• Compact open tubular test area for small footprint, flexible placement and convenient testing.
• Single‑beam parallel light path with dual‑lens dual‑array detector increases detector count and improves optical layout for higher accuracy, lower measurement limit and better resolution.
• Airflow protection device protects the optics from droplet contamination and extends instrument service life.
• Spray‑triggered particle size testing enables instant measurement and immediate data.
• Three software distribution modes (free, R‑R, log) to cover cross‑industry particle sizing needs.
• External automatic mobile platform: SOP‑controlled test positions allow fixed distance testing with one‑click move/return to reduce manual error and improve repeatability.
