The purpose of this app is to help spray applicators use the correct ASABE spray quality for agricultural sprays.  The app identifies an installed nozzle and its spray quality, or suggests a nozzle purchase based on spray quality, manufacturer, flow rate, fan angle, and nozzle type requirements entered by the user. The app produces a list of nozzle candidates, and for each candidate, shows a table identifying the nozzle manufacturer, nozzle type, and model, with recommended pressures and corresponding spray qualities. The database contains all nozzle products for which spray quality information exists from TeeJet, Hypro, Greenleaf, Hardi, Wilger, Lechler, and Albuz.
