This standard double ring infiltrometer set is used for synchronous measurements in triplicate.
The measurement of water infiltration into the soil is an important indication for the efficiency of irrigation and drainage, optimising the availability of water for plants, improving crop yield and minimising erosion.
The double ring infiltrometer is a simple instrument used to determine the infiltration rate of water into the soil. The infiltration rate is determined as the amount of water per unit area and unit time that penetrates the soil. This rate can be calculated from the measurement results and Darcy's Law.
The standard set of the double ring infiltrometer consists of several sets of stainless steel rings with different diameters (for transport reasons). Since vertically infiltrated water flows away to the sides, the outer ring of the infiltrometer serves as a barrier. Measurements are only taken in the inner ring through which the water flows almost vertically.
