Boockmann offers a compact device for a quick and easy measurement of the static coefficient of friction, allowing fast judgement of production conditions and parameters. The measuring principle is based on the start of gliding on an inclination plane whose angle is successively increased starting from zero. Two sections of a wire sample are clamped in a sliding plate and a inclination plate for this purpose, and the sliding plate is placed on the inclination plate so that the wire pairs cross.

For measuring the static coefficient of friction between a cable jacket and conduit material a special model is available.
