Assessing water sensitive paper – Part 3

This is the final part of our three-part article discussing methods for digitizing and processing water sensitive paper. You can read part one here and part two here. Morphological operations We can now move on to the larger shapes, or “morphology” of the objects in our binary image. Our goal is to quantify deposits by […]

Assessing Water Sensitive Paper – Part 2

This is part two of our three-part monster-article on methods for digitizing and processing water sensitive paper. You can read part one here. Image analysis software There are many choices of software designed to analyze digitized WSP images (E.g. Optomax, Stainalysis Freeware, DropVision, ImagePro Plus, DropletScan, AgroScan, DepositScan, UTHSCA ImageTool). Some were developed for aerial […]

Assessing Water Sensitive Paper – Part 1

About this article This is not a typical article for www.sprayers101.com. We like to develop actionable, data-driven content written in an easily-read format. Some articles discuss the results of research, some describe best practices and techniques, and occasionally there’s a song parody. But this article is different. We recently wrote about the three commercially-available brands […]

Comparing three brands of water sensitive paper

Introduction Spray coverage describes the degree of contact between spray droplets and the target surface area. This metric can be used to predict the success of an application. One of the easiest methods for visualizing coverage is to use water sensitive paper (WSP), which is a passive, artificial collector that turns from yellow to blue […]

Diagnosing Airblast Coverage

Assuming there are no mechanical or maintenance problems, water-sensitive paper can be used to diagnose sprayer performance. Go here to read more about water-sensitive paper. Interpreting the results and knowing what changes to make is the critical part of the process. Observing no coverage, or a sodden paper, make for obvious conclusions… but what about everything in between? Here […]
