Multielectrode sensors based on electrochemical impedance spectroscopy (EIS) were developed for monitoring marine atmospheric corrosion in simulated marine environment with various relative humidities and fixed chloride ion content. The results show that at 40-60% RH, EIS results reflect the electrode characters, whereas at 75-100% RH, it is proved that EIS measurements can be used to monitor the atmospheric corrosion rate. The reciprocal of the charge transfer resistance provided quantitative change trend of corrosion rate and showed a similar change trend with the reciprocal of the polarization resistance, which was verified by weight loss.
