STANDARD CERAMIC FOR WIND SYSTEM - SDEC 220

APPLICATIONS

Agronomy/agriculture.
Hydrology, soil mecanics
Permeability studies
Irrigation management
Water potential studies on monolithes (laboratory experiments).
Tensiometric application in the laboratory only.
Ceramic used in the WIND system (INRA-France) for determining k(theta) and h(theta) curves.

Being extremely small, this ceramic is basically used for very specific experimentations.
Its mounting (on nylon capillary 3x1,5mm) demands great care. Warning : because of its tiny inside diameter, it might be difficult to drain air bubbles out of the tensiometric system. You should use it in the laboratory only where it is easier to re-saturate the ceramic.
