PURPOSE: A device for measuring the degradation of a reinforced concrete structure is provided to measure the speeds of a chloride ion and carbon dioxide and the time required until the chloride ion and the carbon dioxide reach the inner steel reinforcements from a structure surface. CONSTITUTION: A device for measuring the degradation of a reinforced concrete structure comprises a supporting stand(100) and a plurality of degradation measuring sensors(200). The supporting stand includes a plurality of supporting units(101) having different height. The measuring sensors are mounted in a plurality of supporting units. The supporting stand includes a body portion and the supporting unit. The body portion is installed in a direction orthogonal to a surface of a reinforced concrete structure(1). The supporting unit is extended to a direction parallel to the surface of the structure and to a lateral side from a lateral surface of the body portion.
