What does a Potometer measure?

Depending on the rate of movement, this could be 10 or 30 seconds or longer. The thesis statement will reflect the kind of paper being written. You can use other experiment designs to look more conveniently, and hopefully more accurately at the three factors that influence the rate of photosynthesis eg Rate of photosynthesis experimental method 2.
