Constant-Falling Head Permeameters
- Humboldt - HM38 Series
For use with granular soils in determining the coefficient of permeability via the constant or falling-head method for laminar flow of water.
Compact and portable unit includes manometer tube, scale and permeameter base attached to a platform. Funnel provides adjustable constant head reservoir. Spring incorporated into top cap to apply 5-10 lbs. force against top stone or screen to prevent soil density changes. End caps and clamping ring of anodized aluminum.
Each set complete with: permeameter; manometer tube; two funnels; either porous stones or perforated screens depending on diameter (6" and 9" used perforated screens), and tubing for connection to water source.
