A corrosion medium is placed in a conductive capacitor of the device; an upper rubber eraser and a lower rubber eraser are plugged at the upper part and the lower part of a metal pipe respectively; the metal pipe is arranged in the corrosion medium of the conductive capacitor; a direct-current positive terminal is connected to the upper end of the metal pipe and connected with an anode of a direct-current power supply through a lead wire; and a direct-current negative terminal is arranged on the outer side surface of the conductive capacitor and connected with a cathode of the direct-current power supply through the lead wire. The corrosion of the nonferrous metal soil is accelerated through an external direct current, so that the corrosion degree of the soil in the test region on the metal material is convenient to quickly judge. Related data of metal soil corrosion (weight loss) can be quickly obtained in 24 hours. The accelerated corrosion test device is simple in structure and convenient in measurement, is not limited by regions and is convenient to carry.
