Mariotte Tubes are used with the HM-128 Double-Ring Infiltrometer to determine the water infiltration rate of the 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. The valve on top is used for venting when filling the tube. Divisions marked in millimeters 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 HM-128 and are also available individually as an additional or replacement item.
HMA-632 has a 3,000ml capacity.
HMA-633 has a 10,000ml capacity.
