PSP - Steel Soil Water Sampler

Suction lysimeters collect pore water from unsaturated soil. A constant vacuum source draws pore water into the lysimeter through a porous,stainless steel membrane. Pore water samples are brought to the surface by applying vacuum or pressure. Suction Lysimeters are most suitable in moist soil (tension less than 500 mbar) and can also be installed below the water table.
