atmometer An instrument that is used for measuring the rate of evaporation of water into air. It is normally in the form of an open-ended glass tube from which water can evaporate. By using an atmometer alongside a potometer, it is possible to compare the rate of transpiration from a plant with evaporation from a purely physical system.
