The infiltration rate of a soil is an important quantity for the design of an irrigation system. This parameter may vary from one soil to another and depends on soil structure and moisture conditions. The Infiltration Demonstration Device, EID210, provides a simple but effective way to observe these complex processes.
The EID210 Infiltration Demonstration Apparatus has 3 Pyrex glass tubes in which the soil samples are placed, the base of the tubes being equipped with a perforated plate that can retain the material while allowing the water to flow. A known volume of water is introduced into each tube and the progress of the infiltration inside the samples is observed. Each cylinder is graduated. A stopwatch supplied with the device allows measurement of infiltration rates.
