Description

Accurate and reliable measurements of stomatal conductance

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

With the SC-1 Porometer, precise stomatal conductance measurements are obtained 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 over the last 15 years.

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

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

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

Quick measurements with the SC-1 porometer

Stomatal conductance measurements are obtained in thirty seconds.

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

The calibration takes just a few minutes. The SC-1 Porometer is a portable, battery-operated device that incorporates a simple user menu.

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

Readings can be recorded as conductance or resistance.
