The 3,000ml Mariotte Tube for the Double Ring Infiltrometer is used with the Double-Ring Infiltrometer to determine the water infiltration rate of soil. The tubes measure water volume and function as a reservoir to maintain a constant head of water during testing. A valve at the base of the aluminum tube is used for filling and draining water. A top valve is used for venting when filling the tube. Divisions marked in millimeter on the side of the aluminum tube show the flow rate through a sight cut-out. The sturdy base plate provides stability.
Both tubes are included with the Double-Ring Infiltrometer and are also available individually as an additional or replacement item.
