The atmospheric corrosion electrochemical measurement device in the environmental test developed by ourselves is introduced, including the working principle, functional use, hardware and software structure and preliminary test results of the Kelvin atmospheric corrosion analyzer. The Kelvin atmospheric corrosion tester developed by ourselves adopts the technique of vibration capacitance and does not need to be in contact with the sample to be measured and the electrolyte. The Kelvin probe is used as a reference electrode to measure the potential of the metal electrode under the liquid film and the polarization curve , Which provides advanced techniques and methods for studying material corrosion in the atmosphere
