摘要

Measuring device for measuring the moisture content in building materials or the like according to the electrical resistance measuring method, wherein the measuring device generates an electrical measuring current which is passed through the building material with measuring electrodes, characterized in that the measuring device (1) introduces a borehole (18) , insulated and elongated measuring tube body (3) with two open ends (4, 5) in which two insulated rod - shaped measuring electrodes (6, 7) are arranged longitudinally displaceable, which at their free ends in the region of the free end (5) of Measuring tube body (3) each have a measuring punch (8, 9) and are connected at their other ends with a handle knob (10) in which an electronic resistance-measuring unit (11) is integrated and located at the other end (4) of Measuring tube body (3) is located, wherein the measuring electrodes (6, 7) are longer than the measuring tube body (3), so that the measuring punch (8, 9) for performing a Mes Move by the operation of the handle knob (10) from the inside of the measuring tube body (3) at its open free end (5) in the borehole (18).
