Most measurements in the soil-plant-atmosphere continuum are fairly straightforward. Measuring stomatal conductance is not. And since stomatal conductance can’t be predicted from theory and must be measured, you need an instrument that’s easy to use. Presenting the SC-1.
Complex science in a simplified package
Backed by solid scientific theory and 15 years of research, the SC-1 is designed to provide you with a simple solution to a complex problem. By measuring vapor flux from the leaf through the stomates, it enables you to tell the difference between transpiring leaves and ones that have shut down. High-speed results, ease of use, and a low cost mean more measurements in less time without blowing your budget.
Accurate readings in seconds
Not only can you make accurate leaf conductance measurements in only thirty seconds, but you can calibrate the SC-1 in just a few minutes. After calibrating, simply clip it on the leaves you are interested in and start measuring stomatal conductance.
Measurement Specifications
Stomatal Conductance
Range: 0 – 1000 mmol/(m2s)
Resolution: 0.1 mmol/(m2s)
Accuracy: ±10% of measurement from 0 to 500 mmol/(m2s)
NOTE: The SC-1 can measure higher than 500 mmol/(m2s) and detect relative stomatal conductance change in the high range, but absolute accuracy becomes unverifiable past 500 mmol/(m2s).
