This work presents the experimental evaluation of a novel methodology for the in situ assessment of corrosion in reinforced concrete structures. The technique is based on dynamic control of the applied current to maintain appropriate polarization conditions. Laboratory tests were conducted on specimens with different concrete types and exposure conditions. The results show improved polarization control compared to previous generations of confined current corrosion meters, with corrosion rate values comparable to reference techniques such as Linear Polarization Resistance and embedded multiparametric systems. The originality lies in ensuring appropriate polarization regardless of corrosion state through a non-invasive approach, demonstrating strong potential as an effective tool for corrosion diagnosis.
