The Guelph Permeameter is an easy to use instrument to quickly and accurately measure in-situ hydraulic conductivity. 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. Measurements can be made in 1/2 to 2 hours, depending on soil type, and requires only about 2.5 liters of water. Measurements can be made in the range of 15 to 75 cm below the soil surface. The Guelph Permeameter is 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.
