ABSTRACT:
An assembly including a tray-like member having a multiplicity of parallel adjacent elongate troughs. Each of the troughs has a major portion adjacent a first edge, and a minor portion adjacent a second edge; and the assembly includes a transparent polymeric sheet sealed over the minor portions of the troughs to define receptacles for liquid. After the major portions of the troughs are positioned beneath the spray zone at a specific distance from the nozzles with the troughs extending transverse of the elongate spray zone and after liquid is sprayed through the spray nozzles upon its upper surface, the assembly can be tipped so that the liquid collected in the troughs will run into the receptacles and the comparative resultant levels of liquid the receptacles will provide a visual indication of the uniformity of the amount of liquid being delivered by the nozzles along the spray zone at the specific distance.
