Double Ring Infiltrometer (SMT-ST-02)

This apparatus is designed to measure the infiltration rate of water into the soil, which is the speed at which water enters the ground surface. It is used to determine the infiltration capacity of soil, a critical parameter for designing irrigation systems, managing water resources, and planning drainage or groundwater recharge projects. The infiltrometer consists of two concentric stainless steel rings, an inner ring and a larger outer ring, that are driven into the ground. The outer ring creates a buffer zone that forces water from the inner ring to infiltrate vertically downward, preventing lateral spread and providing a more accurate, one-dimensional measurement of the infiltration rate. Water is poured into both rings, and the rate at which the water level drops in the inner ring is measured over time to calculate the infiltration rate. Its primary applications are in agricultural science, civil engineering, and environmental hydrology for field studies. The key benefit is its simple yet effective design for obtaining reliable in-situ measurements, enabling users to assess soil permeability, optimize irrigation schedules, and evaluate the suitability of land for stormwater management or wastewater disposal.
