Guelph Permeameter Kit
Soil Moisture Guelph Permeameter Kit

Product Features
 
  • Accurate evaluation of soil hydraulic conductivity, soil sorptivity, and matrix flux potential can be made in all types of soils.
  • The equipment can be transported, assembled, and operated easily by one person.
  • Soil Moisture Guelph Permeameter Kit measurements can be made in 1/2 to 2 hours, depending on soil type, and require only about 2.5 liters of water. 
  • Measurements can be made in the range of 15 to 75 cm below the soil surface.
  • A complete kit consisting of the permeameter, field tripod, well auger, well preparation and cleanup tools, collapsible water container, and vacuum test hand pump, all packaged in a durable carrying case.
  • Accessory attachments are available for extending the measurement capability of the permeameter.
  • Depth attachments increase the depth of operation by 80 cm.
  • The maximum practical operating depth is 315 cm.
  • Ring attachments allow ring infiltrometer measurements from 10-cm and 20-cm diameter rings.
  • A tension adapter allows measurements to be made under tensional and very low head conditions. 
  • Ring and tension infiltrometers are also available as stand-alone units, rather than attachments to a Guelph Permeameter unit.
  • The stand-alone units come as kits which include carrying cases and all items necessary to make measurements. 






Guelph Constant Head Permeameter
Eijkelkamp 09.07 Guelph Constant Head Permeameter

Product Features
 
  • Eijkelkamp 09.07 Guelph Constant Head Permeameter is a ‘constant head’ permeameter that operates in accordance with the principle of the Mariotte bottle.
  • After boring a hole the Guelph permeameter is placed. The water from the permeameter slowly flows into the auger hole and penetrates into the soil.
  • At a certain moment a saturated ‘bulb’ is formed and the out-flow of water from the storage cylinder reaches a constant value (that is measured).
  • These measuring data together with the diameter of the auger hole and the level of the water in the auger hole, are used to determine the (saturated) hydraulic conductivity of the soil.
  • The complete standard set, for measurement up to a depth of 75 cm, fits in a carrying bag and contains the Guelph permeameter, a tripod, drill bits, a vacuumtest manual pump, a fold-up jerry can and various accessories.






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

Product Features
 
  • In case of direct measurement in the field the auger hole method according to Hooghoudt can be applied.
  • The determination of the permeability to water of a soil takes little time (by comparison to other methods), requires a limited number of instruments.
  • A hole is bored in the ground to a certain depth below the groundwater level and after a time the water in the hole will rise to the said water level. The water is consequently bailed out and the time it takes for a new water level to establish itself is recorded. With the help of formulae and/or nomogrammes this rate of water rise can be translated to the average water permeability factor of the different strata of soil.
  • The depth of the bore hole is dependent upon the groundwater level and the thickness and the permeability of the successive layers in the ground profile.
  • Eijkelkamp 09.01.SA Hydraulic Conductivity Test Kit, Model Hooghoudt is standard set (SA) suitable for measurements to a depth of 2 meter.
  • SA contains an Edelman- and a Riverside auger with an upper part and an extension rod, a bailer, measuring tape with holder and float, a filter and a stopwatch.
  • The complete set can be transported in the field in a strong carrying bag.
  • The extendable set (SB) is suitable for measurements to a depth of 5 meter.
  • This set includes the same items as the standard set, however the 1 meter long filter has been replaced by an extendable filter with a total length up to 5 meter (also including extension rods for the auger).






Rainfall Simulator
Eijkelkamp 09.06 Rainfall Simulator

Product Features
 
  • Eijkelkamp 09.06 Rainfall Simulator allows erosion to take place on a small section of the plot. With the apparatus rainfall is simulated on a slanting surface.
  • Through small capillaries in the plate under the water filled cylinder, the drops fall down on the slanting surface.
  • Once fallen to the surface of the soil, the droplet loosens soil particles. These particles jump up and fall down again, slightly lower, on the slope. At the bottom of the slope, water and soil particles are  collected in a reservoir.
  • Through research in the laboratory of the soil particles collected, an indication can be derived concerning the composition and the sensitivity to erosion of the soil under research.
  • By comparing the measuring results to other measuring results, the researcher may set up a scale for sensitivity to erosion of the researched soil.
  • It is important to keep the factors influencing the process (for instance the temperature of the water) as constant as possible.
  • Recommended to gather information concerning the history of the use of the soil. 






Ksat Constant Head Permeameter
Eijkelkamp 09.11 Ksat Constant Head Permeameter

Product Features
 
  • Eijkelkamp 09.11 Ksat Constant Head Permeameter an instrument that provides the means to collect data for determining in situ saturated hydraulic conductivity of the vadose (unsaturated) zone easily and conveniently.
  • The measuring procedure is known as constant head well permeameter technique, shallow well pump-in method or borehole infiltration test.
  • Before the equipment is used a hole is augered (the bottom of the hole must be plane (use the Riverside auger).
  • The main unit is used for measuring hydraulic conductivity to a depth of 2 m.
  • The depth of measurement can be easily increased to 4 m by attaching a set of constant head tubes to the main unit.
  • To measure below 4 m depths, a special flow measuring reservoir and a pressure transducer (available as optionals) are required.
  • The standard set (for a depth of 2 m) contains: the compact constant head permeameter and augers for installation.
