consisting of:

• probe tub with U-tube manometer and weighing table,
• laboratory balance,
• Permeameter hood with sealing and hose connection 

Laboratory permeameter for determination of the saturated hydraulic conductivity of soil samples (kf – value).

A sample ring filled with soil will be flows trough by water by a defined pressure difference. The quantity of water flowing trough the sample is realized by a balance. The hydraulic conductivity kf is computed by the Darcy law on the basis of the effective pressure gradient and the quantity of water flowing trough per time unit.

Advantages:

• Vibrationless installation of the measuring hood over the saturated soil sample in the water tub
• Measurement of the flow rate on very small pressure gradient
• Chose of an optimal flow rate for each soil sample
• Measured value regulation at 10 sample rings with 250 ccm volume
