The SATURO dual head infiltrometer does almost everything for you. It’s fully automated and doesn’t require post-processing of data. Install the ring, connect the hoses, and push start. It’s that simple.
The infiltrometer automatically measures infiltration rates, and the control unit calculates field saturated hydraulic conductivity (Kfs) on the fly. That means if you need a value right away, it’s there. If you want to dig deeper, you can always download the raw data.
Unlike double ring systems, the SATURO infiltrometer is designed for one person to carry and set up. Plus, it requires way less water, saving you a ton of time and effort. How? The SATURO ponds water on top of the soil and uses air pressure to create two different pressure heads. It uses a pump to automatically maintain the correct water levels.
METER is trusted by
Single and double ring infiltrometers require you to know—or guess—the “alpha factor” (soil macroscopic capillary length) to manually correct for three-dimensional flow. The SATURO infiltrometer changes everything. It automates the well-established dual-head method which measures infiltration at two different pressure heads to estimate sorptivity. This simplifies the three-dimensional flow analysis, allowing you to determine field saturated hydraulic conductivity without making any dubious assumptions. And the best part is—it does all the calculations for you, saving you hours of tedium.
A simple, precise solution
The SATURO infiltrometer combines automation and simplified data analysis together in one system. It even computes infiltration rates and field saturated hydraulic conductivity on the fly. And the SATURO is recommended by the Soil Health Institute as a standard method for measuring Kfs: a Tier 1 soil health indicator. The SATURO makes life a little easier for those who need a faster, more accurate way to measure Kfs in the field.
