A potometer measures water loss from leaves. A bubble potometer measures the rate of water loss from a plant by transpiration. A weight photometer measures the amount of water lost by a plant through transpiration. The washing line method is used to prove that most water loss occurs from the lower surface of the leaf.
potometer' (from Greek ποτό = drunken, and μέτρο = measure), sometimes known as transpirometer, is a device used for measuring the rate of water uptake of a leafy shoot which is almost equal to the water lost through transpiration. The causes of water uptake are photosynthesis and transpiration
