• Lightweight and portable for easy transportation.
• Test time of two hours or less.
• Requires only 2.5 liters of water.
The Guelph Permeameter is a constant head permeameter that measures in-situ hydraulic conductivity. It is a simple to operate, portable unit that requires very little training to use. Only one person is needed to perform the test.
The method involves measuring the steady-state rate of water recharge into unsaturated soil from a cylindrical well hole, in which a constant head of water is maintained. Calculations are made to determine the hydraulic conductivity, soil sorptivity and soil matrix flux potential. Depending on the soil type, tests can take between 1/2 hour and 2 hours using only 2.5 liters of water.

The Guelph Permeameter is used to obtain accurate measurements of hydraulic conductivity, soil sorptivity and soil matrix flux potential. These three factors govern how liquids will move through an unsaturated soil profile.
Recent significant advances in both the theoretical and practical techniques of measuring soil hydraulic conductivity have been made by the University of Guelph, Canada. This has resulted in the development of the Guelph Permeameter, utilising the Constant Head Well principle.
