3″ x 1″ Water Sensitive Paper

Water Sensitive Paper is useful for easily and quickly evaluating and monitoring spray applications, including droplet densities, penetration, widths, and distribution. It also helps determine the effectiveness of the spray nozzles and ensures you are using the adequate amount of spray. The special coating on the top side of the paper becomes tinted with dark blue dots following exposure to dissolved spray droplets while the opposite side repels water.
