About This Product
Soil permeability describes how water flows through a soil in its natural condition, and this apparatus measures it in the laboratory using a constant or variable head. Pressure points along the cylinder connect to the manometer stand and the constant level tank. The constant head method suits relatively coarse soils, while fine grained clay-like or silty soils are tested with the falling head apparatus. Beyond India, the Constant Head Permeability Apparatus is available for export to Grenada, Namibia, Luxembourg, Central African Republic and Jordan.
Frequently Asked Questions
Which soils suit the Constant Head Permeability Apparatus?
