Decagon SC-1 Porometer
The SC-1’s breakthrough steady-state technology makes getting accurate stomatal conductance measurements affordable and practical for everyday research.
Plant water use is now more than easier to measure with the SC-1 Leaf Porometer. Stomatal conductance readings are recorded in about 30 seconds. The SC-1 allows scientists and growers to gain greater insight into plant water relations and water use strategies.
Measurements from the SC-1 Leaf Porometer can be used in various fields of science including to estimate transpiration, Penman-Monteith evapotranspiration, hydrology models, irrigation scheduling, and more.
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.
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).
