The Sensor Head
The Leaf Porometer cannot take measurements without the
aid of the sensor head. This sensor head is responsible for
gathering the information (vapor pressure, humidity, etc.)
that the Leaf Porometer uses to calculate stomatal conduc-
tance in a leaf. The following illustration shows the external
components of the sensor head.
