Double Ring Infiltrometer Test
Heavy-Duty Infiltration Rings – 6 in & 12 in
The Double Ring Infiltrometer is a reliable field tool used to measure soil infiltration rates. These heavy-duty infiltration rings are ideal for quick and accurate testing in hard or rocky soils.
This equipment is widely used with soil testing equipment by engineers, environmental professionals, and students.
Product Overview
The Heavy-Duty Double Ring Infiltration Rings include:
- 6 in inner ring
- 12 in outer ring
- 4 in height
Both rings are inserted approximately 2 inches into the soil and filled with water. The drop in water level inside the inner ring is measured over time to calculate the infiltration rate.
Using two rings helps reduce lateral water movement and improves test accuracy.
Heavy-Duty Construction
These infiltration rings are built for repeated field use.
- Made from 16-gauge galvanized steel
- Rust-resistant for long service life
- Designed for rocky, compacted, or hard soils
- Beveled edges for easy soil penetration
- Welded rings for proper alignment
- Rubber-grip handle for easy installation
They are commonly used alongside geotechnical testing equipment.
Why Proper Installation Matters
Correct placement directly affects test results.
- Rings must be level and evenly inserted
- Penetration depth must be consistent
- Rings must stay centered during installation
Optional accessories such as centering pins, splash guards, and support stands help improve test accuracy and repeatability.
How the Double Ring Infiltrometer Works
- Insert both rings into the soil
- Fill the inner and outer rings with water
- Maintain a constant water level
- Measure the drop in water level in the inner ring
- Calculate the infiltration rate over time
The outer ring limits sideways water flow, ensuring vertical infiltration measurement only.
This method aligns with ASTM D3385 standards and is commonly used with field testing equipment.
Get Results Fast
One of the key advantages of this system is speed.
- Results often available in as little as 15 minutes*
- Ideal for time-sensitive field work
- Requires minimal water
- Easy one-person operation
*Note: Short tests do not include full soil saturation. Moisture sensors may be used for verification.
Typical Applications
These infiltration rings are commonly used to test:
- Golf greens, tees, and fairways
- Sports fields and playgrounds
- Lawns and landscaped areas
- Wetlands and drainage fields
- Septic systems
- New construction sites
- Farms and forestry land
They support irrigation planning, drainage design, and soil permeability studies.
Factors Affecting Test Results
Several conditions can influence infiltration rates:
- Soil type and structure
- Clay content
- Moisture level
- Temperature
- Chemical composition
Always document site conditions during testing to ensure reliable data.
