Lysimeter SW 070 series

Suction cells collect pore water out of unsaturated soil. A constant vacuum source draws pore water into the cell through a porous stainless stell membrane. Pore water samples are brought to the surface by applying vacuum or pressure. Suction cells are most suitable in moist soil (tension less than 500 mbar) and can also be used below the water table.
