There are a few works undertaken to verify the accuracy of corrosion measurements. In general, it is assumed that potentiostats are correctly fabricated and then efforts are made to check the repeatability of certain measurement types as polarization curves, with the same or different operator or to calibrate corrosion rate measurements with gravimetry. This paper makes a more in-depth study about repeatability and reproducibility of the measurements and deals with the comparison of corrosion parameters measured in concrete with various degradation types such as carbonation or chloride attack. Different field and laboratory devices were compared.
