Qt-in12-w Double Ring Infiltrometer

Application:
Double ring infiltrometer is a simple instrument, used for testing theA hydraulic conductivityA of soils. The hydraulic conductivity is the flow of water to seep into the unit surface area per unit time. TheA infiltration rateA can be calculated by measuring results and Darcy's law.

The standard device includes several sets of different diameter stainless steel ring, which can deal with several measurements in the same time to get accurate and reliable results. When vertical penetration flows to the edge, the outer ring of the infiltrometer will play a role in isolation. The water in the inner ring flows perpendicularly, thus measuring only processes in the inner ring. Press these two rings into the soil for a few centimeters by the driver disk and energy-absorbing hammer, then you will get the infiltration rate. Because the inner and outer rings are filled with water, the water is actually vertically flow from the inner ring into the soil. To achieve a satisfactory result, be sure to consider the following factors that may affect the measurement: surface vegetation, compaction degree of soil, soil temperature and soil layers (stratum). The best measurement results are derived according to the soil on - site water holding capacity.
