CERAMIC SUCTION LYSIMETERS Ø 31mm & Ø 63mm - SPS 200

Groundwater pollution is now a well known problem around the world. The danger occurs when polluting molecules leach through the soil and into a water sheet supplying a drinkable water tank.

The SPS 200 soil solution sampling system is a simple equipment built to help environmental scientists study the movements of molecules in the soil. It can extract water from cultivated soils or any other type of soil.

The principle on which the SPS 200 works happens to be cheap, quick and most of all efficient. The soil water is drawn into the porous ceramic cup.

It will only take two days to collect enough solution in order to have it analysed (nitrate, pesticide or other molecule’s concentrations, measuring out fertilizers ...).

Key Advantages

IMPORTANT VOLUME OF SOIL SOL. COLLECTED
EASY TO USE
COST EFFECTIVE

Disadvantages
Not chemically inert with all elements or molecules

GENERAL TECHNICAL CHARACTERISTICS

This system collects the soil water which is freely moving in the soil. The system works as long as the soil water potential is in the 0 / -850 mbar range.

Working principle :
A porous ceramic cup is fixed on the bottom of an empty PVC tube. The tube is introduced into the soil in order to collect the soil solution.
After creating a depression inside the tube (with vacuum pump ref. SPS 400), the soil solution is drawn from the soil trough the porous ceramic cup and into the tube.
After a few days, a vacuum pump (ref. SPS 400 or PAV 2000 ) and collection flask are used to collect the soil solution contained in the SPS tube. The soil solution is then transfered into a sampling flask which is brought into the laboratory to have its content analysed. The solution can also be analysed in the field with a field analyser, reflectometer (ref. 169700001).

The porous ceramic cup used for the SPS 200 system exists in two different diameters (31mm and 63mm). This enables you to work eventually with different volumes of collected solutions. The 63mm ceramic cup (SPS 200-63) will collect twice as much soil solution as the 31 mm ceramic cup (SPS 200-31).
