Abstract

Equipment is described that assists experimental work on controlled-drop application techniques. An electronic tachometer measures centrifugal nozzle rotational speeds in the range 0 to 5000 rpm. Speed control is achieved with a simple regulator incorporated in the tractor electrical system. Both devices are also suggested as worthwhile additions to commercial spray rigs.
