PRO-Water Sensitive Paper 1x3 50 pack Laboratory Grade measures to 30 microns SpotOn® Paper Pro is engineered for precision spray analysis, delivering professional-grade performance for laboratory, research, and advanced application testing. With the ability to detect droplets as small as 30 microns, it is ideal for evaluating ultra-fine sprays, drift potential, and detailed coverage patterns where accuracy is critical. SpotOn® Paper Pro produces a more uniform blue color response than standard Spot On Paper providing clearer droplet definition, stronger contrast, and more reliable interpretation of spray performance. The paper also resists warping in humid conditions and is packaged in resealable, protective packaging to maintain integrity after opening. What you don't know can hurt you. Visualize your coverage and be able to test different variables from water rate, to pressure, and additives to see how they effect coverage in YOUR SPRAYING SYSTEM SpotOn Paper allows for quick and easy spray visualization: visualize spray coverage, visualize droplet size and uniformity and visualize off target application. Papers have a suggested use date on the resealable package. There is software available that may work with your mobile computing device to give a more accurate indication of coverage.
