Abstract: A method of verifying measurements of a spray pattern from a nozzle is provided. The method includes inserting the nozzle through an opening in a bottom wall of a closed spray testing container. The closed spray testing container includes a pair of side walls and a pair of end walls connected to the side walls. A top wall is opposite the bottom wall and is connected to the pair of side walls and the pair of end walls to provide a volume. The top wall is transparent. The bottom wall includes at least one of a scale and a spray pattern representation provided on a surface of the bottom wall. At least one of the scale and the spray pattern is used to verify a spray pattern provided using the nozzle.
