Fison Oil Particle Counter quantifies particulate contamination in oil across a 0.8–600 µm range, with 64 channels and sampling volumes from 0.2 to 6000 mL. The high-resolution semiconductor laser detects particles by size, while the built-in data analysis system calculates particle counts and pollution levels. Manufactured for oil cleanliness testing in petroleum, metallurgy, and machinery industries, this Oil Particle Count Testing Equipment supports fluid contamination evaluation.
