|Criteria||Double Ring Infiltrometer||Single Ring Infiltrometer||Philip Dunne Permeameter||Minidisk Infiltrometer||Guelph Permeameter||Tension Infiltrometer|
|Volume of Water Needed||Medium||Low-Medium||Low||Low||Medium||High|
|Other advantages||ASTM D3385 standard for measurement||Simpler to use than double ring infiltrometer||Easy to install in ground. Multiple measurements can be made quickly||Simplest of devices||May be used to measure infiltration at depth (up to 2.5 ft)||Measure unsaturated hydraulic properties of soil|
|Measure unsaturated hydraulic properties of soil||Requires large volume of water in permeable soils||Requires large diameter to be accurate (minimize edge effects)||Need to measure initial and final soil moisture content||Small diameter -many measurements need to be made to ensure accuracy||Small diameter -many measurements need to be made to ensure accuracy||Typically need a sand base to ensure contact between soil and infiltrometer|
