How does a Pressure Chamber Work?

In simplest terms, the pressure chamber can be thought of as measuring the “blood pressure” of a plant, except for plants it is water rather than blood, and the water is not pumped by a heart using pressure, but rather pulled with a suction force as water evaporates from the leaves.

Which Instrument is Best for Me?

We manufacture 12 different instruments. These instruments can be grouped into two categories to help you select the right one.
