DESCRPTION
The SC-1 Leaf Porometer is a battery-operated, menu-driven device used to measure stomatal conductance of leaves. The Leaf Porometer measures stomatal conductance by putting the conductance of a leaf in series with two known conductance elements, and comparing the humidity measurements between them.
SC-1 Leaf Porometer Features
Accurate, Affordable, Practical Stomatal Conductance
The SC-1’s breakthrough steady-state technology makes getting accurate stomatal conductance measurements affordable and practical for everyday research.
No Moving Parts
The SC-1’s steady state design means that it has no moving parts. It leaves the environment alone, and instead determines stomatal conductance by measuring the actual vapour flux from the leaf through the stomates and out to the environment.
Lightweight, Easy to Carry
The porometer weighs about half a pound (300g). You don’t have to haul it around the field with a neck strap; and if you get tired of carrying it, you can put it in your pocket.
Save and Download Data
Readings can be displayed as either conductance or resistance and saved for downloading later (RS232 cable and download utility software included).
ABOUT THE SC-1 Leaf Porometer
The Leaf Porometer measures the stomatal conductance of leaves by putting the conductance of the leaf in series with two known conductance elements. By measuring the humidity difference across one of the known conductance elements, the water vapour flux is known. The conductance of the leaf can be calculated from these variables. We know the humidity at three places: inside the leaf, and at both of the humidity sensors. The Leaf Porometer effectively calculates the resistance between the inside and outside of the leaf: the stomatal conductance. It measures resistance between the leaf and the first humidity sensor and the first and second sensors.
