The permeameter is a laboratory tool to measure the saturated permeability, or K-factor, of soil samples. It's available in several variations: with an open or closed system, suitable for 5, 10 or 25 samples, and for use with soil sample rings with an external diameter of 2.1 or 2.4 in (53 or 60 mm).
Permeability, or K-factor, refers to the capacity of the soil to drain off water. It is determined on one hand by the geometry of the complex of pores, depending on the texture and structure of the soil, and on the other hand on the intrinsic features of the soil solution (viscosity and density).
The soil water permeameter can be used to measure the saturated permeability of undisturbed soil samples in sample rings. The permeability factor gives accurate information about:
This data can help draw further conclusions about
Open vs. closed system
The permeameter is available as an open system, or a closed system with a water pump. The advantages of a closed permeameter compared to an open system are:
|Soil water permeameters|
|Maximum number of samples||5 to 25|
|Power supply||line voltage|
|Reading accuracy||1 ml|
|Sample stored in||Ring|
|Package size||33.5 x 24.8 x 45.3 in | 85 x 63 x 115 cm|
|Weight||66 lbs | 30 kg|
