A measuring device for measuring peak pressure and skin friction in a substrate has a probe body which is to be driven into the substrate to be measured, a first detecting arrangement in the body and serving to detect peak pressures which develop as the body is driven into the substrate, a second detecting arrangement also in the body and operative for detecting skin friction which develops as the body is driven into the substrate, and separate conductors connected with the first and second detecting arrangement, respectively, for carrying signals which originate in the same.
