A device and method for measuring the antifouling coating leach rates on ships hulls uses a spherical segment shaped shell that circulates water over a coated area. A pump connected in closed circuit with the shell assures proper flow rate, A second pump creates a partial vacuum and holds the shell on the coated surface. A combination of nozzles and outlet fittings assures that the coating is exposed to a circulating flow of water. A portion of the circulated water is passed through a cupric ion electrode sensor which provides signals representative of the dissolved copper in water over time and, hence, the leach rate of the coating.
