Casagrande type cells

Sireg Geotech produces Casagrande type cells made of sintered quartz.
These instruments have a porous element connected to the ground surface by two tubes of different length (flow pipe and return pipe), in order to take level and piezometric measures in confined aquifers.
Sireg Geotech produces Casagrande quartz sintered cells, possibly protected by microslotted pipe or armored, according to customer requirements.
