An atmospheric corrosion probe has been developed to measure corrosion rates under atmospheric conditions. The corrosivity of the atmosphere as well as the corrosion rate of materials can be accurately
determined. The performances of this new technology are evaluated with experiments that alternate between wet and dry exposure conditions. The onset of the dew point is easily detected. These different measurements show the high sensitivity and high accuracy of these atmospheric corrosion probes. The outstanding capabilities of these corrosion probes to measure low values of corrosion rate are demonstrated.
