Water Permeability Tester© Prof. Lars Appel, Ph.D. (Eng.)

This testing device applies a water column of constant height to a cylindrical test specimen. The water is allowed to flow through the test specimen in either a vertical or horizontal direction for a specified period of time. The resulting water flow rate Q is a calculated measure of the permeability coefficient K. The test is conducted at ambient temperature.
