SC-1 Porometer to measure the stomatal conductance - Leaf Porometer

Quick measurements with the SC-1 porometer

Stomatal conductance is one of the most difficult parameters to measure of the soil-plant-atmosphere continuum.

The SC-1 Porometer provides accurate stomatal conductance measurements quickly and easily.

The SC-1 Porometer measurements are based on steady state theory and a continuous process of research, improvement and development carried out by the METER Group team for the past 15 years.

Stomatal conductance is measured after placing a sheet in series with two known conductance elements (humidity sensors).

By measuring the difference in humidity of these humidity sensors, the flow of water vapor is known.

Leaf conductance values ​​are calculated from these variables, since humidity is known at three points: on the leaf and on the two humidity sensors.

Stomatal conductance measurements are obtained in thirty seconds.

It is necessary to calibrate the equipment in the field and whenever the environmental conditions during the sampling change.

Calibration takes a few minutes. The Porómetro SC-1 is a portable device that works with batteries and that incorporates a simple user menu.

The equipment is light, has memory for more than 4000 data and allows download via cable (USB cable and management program included).

Readings can be recorded as conductance or resistance.
