Disclosed is a method for determining the swellability and the swelling kinetics of superabsorbent material () such as polymer gels, for example, which comprises introducing a defined volume of the dry superabsorbent material () into a measuring vessel (), using a movable element () within said measuring vessel () to apply a restraining force () to said superabsorbent material () and capturing the expansion of said superabsorbent material () contactlessly within a chamber () in a continuous manner by capturing the change in height of a piston () which bounds said chamber (), travels in a measuring vessel () and is marked with a height scale ().
