It has a couple of 3 m long rails, along which the nozzle under test moves while spraying, controlled by a closed-loop position and speed controller. The design of the equipment was mainly based on the ISO 5682-1 standard. This study describes a low-cost laboratory test bench able to analyze agricultural spray nozzles under realistic conditions. Abstract: Droplet size distribution is probably the most important feature of a spray as it affects all aspects of a phytosanitary treatment, i.e., biological, environmental, and safety aspects. The system allows for testing nozzles under effective work conditions at different pressure and flow rate values. Featured Application: A low-cost test bench to evaluate spray quality of agricultural nozzles was designed and built.
