Electrochemical sensors for atmospheric corrosion monitoring. This method allows for real-time measurement of corrosion current, thin-film electrolysis conductivity and coating performance by two-electrode Electrochemical sensors, providing more detailed instantaneous corrosion data than traditional mass loss and resistance Sensors techniques. The standard applies to corrosion measurement in a variety of environments, including laboratory, outdoor and real service environments. The method not only provides insight into the atmospheric corrosion process, but also provides a scientific basis for corrosion protection measures and material performance evaluation. Electrochemical sensor continuous data recording allows for a more accurate assessment of atmospheric corrosion effects than Miscellaneous assessment methods such as mass loss specimens and coating test plates.
