This abstract discloses a testing apparatus for quantitatively measuring the creepability property of liquids, especially tracer liquids, such as penetrants and leak tracers. The preferred embodiment of the apparatus essentially comprises a rotatable, cylinder-like shaped base memeber having a longitudinal indentation therein substanially in the shape of a V, with a depression at the vertex of the V and, a metal, rectangularly-shaped panel member having a plurality of adjacent, straight, parallel-spaced grooves therein which are perpendicular to the bottom end of the panel member, with the grooves having length markings therealong indicating the distance from the bottom end, and with the panel member positioned by its bottom end in a vertical-like angled attitude in the depression of the V-shaped longitudinal indentation in the rotatable base member. When the liquid to be tested for creepability capability is poured into the V-shaped base member indentation, the liquid creeps up the grooves in the panel member. The creepability of the liquid can be quantitatively determined from the length markings along the grooves reached by the liquid.
