Soil Infiltration

Double Ring Infiltrometer
Eijkelkamp 09.04 Double Ring Infiltrometer

Product Features
  • Eijkelkamp 09.04 Double Ring Infiltrometer used to determine the rate of infiltration of water into the soil.
  • The rate of infiltration is determined as the amount of water per surface area and time unit, that penetrates the soil. This rate can be calculated on the basis of the measuring results and the Law of Darcy.
  • The standard set consists of a number of sets of stainless steel rings with different diameters (for reasons of transportation).
  • Several measurements can be executed simultaneously, yielding a very reliable and accurate mean result.
  • As vertically infiltrated water runs away to the sides, the outer ring of the infiltrometer serves as a separation.
  • The measurements exclusively take place in the inner ring through which the water runs virtually vertical.
  • It is important to take into account several factors that may influence the measurement: the surface vegetation, the extent to which the soil has been compacted, the soil moisture content and the soil layers (strata).
  • The best measuring results are obtained at ‘field capacity’ of the soil.
  • Used for determining the rate of infiltration and capacity for irrigation and drainage projects, studying drainage, determining the intensity of artificial precipitation and the effect of treatment of the soil.

Tension Infiltrometer
Eijkelkamp 09.01.SA Hydraulic Conductivity Test Kit, Model Hooghoudt

Product Features
  • Eijkelkamp 09.01.SA Hydraulic Conductivity Test Kit, Model Hooghoudt is measures the hydraulic properties of unsaturated soil.
  • Water held under tension infiltrates into a dry soil through a highly permeable nylon membrane.
  • The time dependent infiltration rate is used to calculate unsaturated hydraulic conductivities and related hydraulic properties.
  • Infiltration rates are recorded manually.
  • With the pressure transducers, which can be connected to a datalogger, the rates can also be read electronically. The pressure transducers can be attached to the top and the bottom of the water reservoir.
  • Standard set contains a tension  infiltrometer with separate base plate, a small hand-operated vacuum pump for use during calibration, a metal ring and spare nylon mesh screens.
  • Pressure transducers and a datalogger are optional items.
