Manual infiltrometer

The I1-Inf-tec manual infiltrometer is used to determine the percolation rate of water in turf in order to regulate irrigation flows, save water, and minimize surface runoff.

The infiltrometer has been used by hundreds of colleges, universities, and government agencies. It is reliable and built to last over time.

Advanced Features: Method of Use

Simply set the timer for 15 minutes and insert the double ring cutting blades into the soil until the depth limiting ring sits against the surface. Then, fill both rings with clean water and start the timer.

Fifteen minutes later, when the timer rings, the position of the pointer on the scale indicates the rate of water infiltration in inches or millimeters.

To determine the infiltration rate per hour, simply multiply the result by four.

Site planning

Scheme of Uses

SATURATED EST (most reliable method): Place the infiltrometer directly on the soil to be tested. Fill the rings 2–3 times to allow water to percolate between the pores. Once the soil is saturated, the test can begin.
HUMIDITY TEST (quickest method): Uses a humidity sensor to take readings at 2.5, 5, and 7.5 cm depths.
TEST ON IRRIGATED AREAS: Conduct the test approximately one hour after irrigation. Make sure no precipitation occurred in the previous 48 hours.
ENVIRONMENTAL TESTING: Used for testing containment areas of fuel tanks and for calculating spill cleanup times.

Reading Interpretation

Infiltration data can vary across areas due to vegetation cover, organic matter content, soil compaction, structure, and other variables. Therefore, readings should not be considered conclusive.

To ensure consistency, record the infiltration rate for each area to compare results over time, especially after environmental or structural changes.

How to Use Your Readings

Infiltration data can be used to adjust water volumes for each irrigation zone. Excess surface water reduces oxygen in the soil, limits root development, and increases disease risk.
