There are two main types of potometer used in schools – the mass potometer, which measures transpiration through the loss of mass, and the moving-bubble potometer, which measures water uptake by the shoot.

This design of potometer allows students to combine both measurement techniques, by placing the potometer on a balance, and recording both the change in mass and the volume of water taken up.

Potometer - Wikipedia, the free encyclopedia

There are two main types of potometers used - the bubble potometer (as detailed below), and the mass potometer. The mass potometer consists of a plant with its root submerged in a beaker. This beaker is then placed on a digital balance; readings can be made to determine the amount of water lost by the plant. It is important to note that the mass potometer measures the water lost through transpiration of the plant and not the water taken up by the plant.
