Advancing soil, plant and environmental decision making


The MINI-PAM-II Porometer is a new leaf-clip for the MINI-PAM-II for combined measurements of stomatal conductance and chlorophyll a fluorescence. It measures water evaporation and stomatal conductance of plant leaves and needles to determine stomatal function, which is strongly influenced by stress factors acting on the plant.

This new device is a powerful tool for rapid screenings, high-throughput stress evaluations, or detailed plant analysis with well-established protocols like induction-curves or light-curves. Being lightweight and compact, the device is ideally suited for research from the field to the laboratories. With the built in GPS, accelerometer, gyroscope, and magneto scope sensor the porometer adds geospatial information including angle of incidence of sun radiation and the leaf angle.
