Perméamétre à charge constante
For determining the permeability of coarse-grained soils (sand, gravel, aggregates). These devices enable the permeability coefficient to be measured in the laboratory by passing water through a sample placed in a transparent acrylic cell, connected to a measuring panel and a water reservoir maintained at a constant level. International standards: BS 1377:5, ASTM D2434 and AASHTO T21. Kit contents:
- Manometric measuring panel fitted with 3 glass manometric tubes with graduated scales, connecting tubes and various fittings. Dimensions: 150 x 60 x 1300 mm. Weight: ~5 kg.
- Constant-Level Tank made from acrylic plexiglass, designed for wall mounting. Inlet, outlet and overflow valves are height-adjustable to maintain a constant water pressure during the test. Weight: ~3 kg.
