SC-1 Leaf Porometer

Accurate, Affordable, Practical Stomatal Conductance using SC-1 Leaf Porometer from Decagon Devices
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 vapor flux from the leaf through the stomates and out to the environment.
Lightweight, Easy to Carry
The porometer weighs about half a pound (300 g). 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).

Applications:

  • Plant water use and water balance.
  • Water stress measurements.
  • Uptake of herbicides, ozone and other pollutants.
  • Research on stomatal functions.
