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.
