Corrosion inhibitor performance evaluation device

The utility model relates to the technical field of corrosion inhibitor performance evaluation devices, in particular to a corrosion inhibitor performance evaluation device which comprises a storage box, a collecting hopper is arranged in the storage box in a sliding mode, and an evaluation assembly is arranged on the base face of the storage box. The condition that a sample wafer is corroded when a corrosion inhibitor is not added can be tested through the test box on the left side, and the condition that the sample wafer is corroded when a corrosive agent is added can be tested through the test box on the right side, so that the performance of the corrosion inhibitor can be well evaluated through comparison of the two conditions, and the placement plate can slide out from the interior of the test box through the arrangement of the placement plate. According to the corrosion inhibitor testing device, the sample piece on the placing plate can be replaced, different sample pieces can be tested, the performance
