SC-1 Leaf Porometer. Leaf Porometer Operator’s Manual 2. About the Leaf Porometer 3 2. About the Leaf Porometer The Leaf Porometer is a battery-operated, menu-driven device used to measure stomatal conductance of leaves. Sto-matal conductance is a function of the density, size, and degree of opening, of stomata, which are pores in plants that open to the outside air. A single button on the porometer head permits one-handed use. Consecutive readings can be taken, evaluated and stored just by pressing this button. Stable readings are denoted by the sound of a double "beep". Two porometer cup shapes are provided for different leaf shapes. The head and case are relatively light, and a padded shoulder bag.

The AP4 Leaf Porometer measures diffusion conductance by comparing the precise rate of humidification within a small cuvette (chamber) to readings obtained with a calibration plate. The plate has 6 diffusion conductance settings whose values have been accurately determined by finite element analysis. The leaf porometer will produce an alert when the calibration is complete. If ten calibration measurements are taken and don’t achieve stable readings, see calibration chapter in user manual for troubleshooting tips. Watch the Recording. The LI is a compact porometer with an optional Pulse-Amplitude Modulation (PAM) fluorometer that measures stomatal conductance and chlorophyll a fluorescence over the same leaf area. Capable of completing a measurement in seconds, the LI provides the speed and precision required by researchers today.
