SC1 Leaf Porometer

Accurate, Affordable, Practical Stomatal Conductance

The SC1 Leaf Porometer makes accurate stomatal conductance measurements affordable and practical for everyday research.

No Moving Parts

Steady state design means that it has no moving parts. The SC1 leaf porometer leaves the environment alone, and instead determines stomatal conductance by measuring the actual vapor flux from the leaf through the stomates and out to the environment.

Lightweight, Easy to Carry

The leaf porometer weighs about half a pound (300 g). You don't have to haul it around the field with a neck strap. If you get tired of carrying it, you can put it in your pocket.
