How to set up a potometer a level
WebNext, the potometer is set up according to the manufacturer's instructions. This typically involves filling the reservoir with water and attaching the plant to the potometer using a rubber band or similar method. Once the potometer is set up, the experiment can begin. WebWe can investigate the effect of different environmental conditions (such as temperature, humidity, light intensity and wind movement) on the rate of transpiration using a piece of apparatus called a potometer. A mass potometer measures a change in mass of a plant as a measure of the amount of water that has evaporated from the leaves and stem.
