• Determines infiltration rate of various soils.
• Heavy-duty aluminum rings for rust resistance and long life.
• Graduated Mariotte tubes for inner and outer rings.
The Double-Ring Infiltrometer provides comparative information that is useful for determining erosion rates, leaching and drainage efficiencies, irrigation patterns, rainfall and evaluation of potential septic tank disposal fields.
The instrument consists of two concentric rings, driving cap, two graduated Mariotte tubes, square neoprene splash guards and complete instructions. The two rings are driven into the ground and filled with water. The outer ring acts as a barrier to encourage only vertical flow from the inner ring.
