MEASURING DEVICE FOR MOISTURE OF CONCRETE, MORTAR, WOOD, OR THE LIKE

PROBLEM TO BE SOLVED: To provide a moisture-measuring device that has an allowance related to the pressing angle of an electrode against a measured object and allows measurement, with measurement depth changed. SOLUTION: In the moisture-measuring device, the opposite ends of a gripping body 41 are provided with a detector 42A for measuring the deep part, having a positive electrode 3 having a curved pressing surface to the measured object and a negative electrode 4 that faces the positive electrode 3 at the other end surface of a cylindrical insulator arranged in the center of one end surface of the positive electrode 3, and a detector 42B for measuring the shallow part where the interval between the positive electrode 3 and the negative electrode 4 is set smaller than that in the detector 42A for measuring the deep part. The capacity, corresponding to the deep part and shallow part, is determined by a deep part measuring circuit and a shallow part measuring circuit, the moisture values of the deep part and shallow part of the measured object are determined by a calculation circuit, and they are displayed by a display part.
