Spray quality is categorized based on Dv0.1 and VMD droplet sizes. Data (e.g. VMD) can vary between testing equipment and method, and is provided as an educational resource only to compare series of Wilger spray tips. All testing is done with water, in controlled conditions, so data may not be replicated in real life conditions.
