Leaf Porometer model SC-1

Leaf Porometer is a lightweight, menu-driven instrument for measuring stomatal conductance. It does this by putting a leaf in series with two known conductance elements, and comparing the humidity measurements between them. This new porometer has two modes, automatic or manual. The auto mode eliminates subjectivity of measurement by calculating the final conductance based on measurement of conductance over a set period of time. You can also make your own final determination of conductance by using it in the manual mode.

Product Description

Applications
Water use and water balance.
Water stress measurements.
Herbicide and pollutant uptake studies.
Research on stomatal functions.
Teaching and student labs.

The Leaf Porometer has an easy-to-use menu driven interface, allowing you to use and manage your data. You can also add notes and comments to your saved data for later data analysis. The Leaf Porometer includes a user-friendly software utility for downloading data to your computer.
