A portable apparatus for testing slip resistance of surfaces such as floors and bathtub surfaces operated by applying a pad of friction material to the surface and instantaneously applying a load to the pad at a selected angle. The load is applied by releasing a weight carried atop an articulated linkage on the bottom of which the friction pad is attached. The linkage slides in a frame which can be set at selected angles on a base, and a trigger bar mounted in the frame interacts with a rod of the articulated linkage to hold and release the weight.
