Giatec XCell™ is a smart tablet-based NDT probe for fast, accurate and efficient detection and on-site analysis of corrosion in reinforced concrete structures. Giatec XCell™ meets all the requirements of the ASTM C876 standard specification. Giatec XCell™ benefits from an advanced Bluetooth-enabled maintenance-free sensor that measures the corrosion potential and sends it wirelessly to a tablet for generating half-cell contour plots (i.e. corrosion maps) in real-time. The results can be shared easily with the engineering office. Giatec XCell™ significantly reduces the labor cost associated with the data collection and subsequent contour plot generation and reporting.


Giatec XCell™ can be used for efficient and accurate corrosion mapping according to the ASTM C876, "Standard Test Method for Half-Cell Potentials of Uncoated Reinforcing Steel in Concrete". The results are analyzed using the Android-based application onsite for the identification of locations with high probability of corrosion. The output includes an equipotential contour map for the examined area. The measured potential value are indicative of corrosion probability as presented in Table 1. The countour plots are color coded for more clarity.
