Potometer
The potometer uses the Pressure (Differential) sensor and an accessory pack to measure the transpiration rate of a plant leaf. A large dock leaf, for example, is attached to a water-filled tube, which is then arranged with a small syringe, to damp the pressure changes, and the Pressure (Differential) sensor can then log the steady use of water by a leaf. The data below relates specifically to the Pressure (Differential) sensor.
