XCellTMNDT Device for Half-Cell Corrosion Mapping
Fast, reliable, & efficient detection of corrosion in reinforced concrete structures
Fast, reliable, & efficient detection of corrosion in reinforced concrete structures
This non-destructive testing device uses a probe outside the concrete to detect the location of corroded reinforcing steel.
XCell is a non-destructive testing device for fast, reliable, and accurate detection and analysis of corrosion in reinforced concrete structures, complete with accurate contour mapping.

Yes. However, the user requires a product key to activate the Android application. The product key is unique number that is provided with the XCell sensor. Moreover, the Android device should have wireless 4.0 LE connectivity.
A verification kit is available to purchase with the XCell package. It is recommended to verify the device using this reference electrode before conducting a corrosion mapping project. In case the XCell readings are not in range, the device must be calibrated by our technical support team.
Yes, according to the half-cell test standard, a hard-wire connection to the steel rebar is required.
Corrosion map can be developed for a non-flat surface as the measurements are single points. But, it should be noted that delaminated surfaces cannot be tested since there is no physical contact between the concrete and rebar.
A: The XCell™ probe utilizes a silver/silver (I) chloride electrode in saturated KCl solution. Unlike the conventional copper-copper sulfate electrodes, the XCell™ electrode does not need changing the electrode solution. The electrochemical potential values measured by XCell™ are, however, shown based on the Cu/CuSO4 electrode according to the ASTM C876 specifications which state in section 5.1.1.3 that:
“Other reference electrodes having similar measurement range, accuracy, and precision characteristics to the copper-copper sulfate electrode may also be used. Calomel reference electrodes have been used in laboratory studies. For
concrete submerged in seawater, using silver-silver chloride reference electrodes avoids chloride contamination problems that may occur with copper-copper sulfate electrodes. Silver/silver chloride/potassium chloride reference electrodes are also applied to atmospherically exposed concrete. Potentials measured by reference electrodes other than saturated copper-copper sulfate should be converted to the copper-copper sulfate equivalent potential. The conversion technique can be found in Practice G3 and “Reference Electrodes, Theory and Practice” by Ives and Janz.”
A: All three packages utilize the advanced maintenance-free electrode that has wireless connectivity. They are packaged with the other parts e.g. cables, charger, etc. in a hard carrying case. The main difference between these packages is as follows:
