Compact, lightweight detection systems for detection and analysis of rebar positions and concrete thickness in concrete structures.


The TC-100 series of compact, lightweight rebar detection systems offer the power of nondestructive pulse-induction technology for the detection and analysis of rebar positions and concrete thickness in concrete structures. The instruments are compact, accurate, solid and can stand the harshest environments. The user interface is easy to operate and does not require special skills. The systems detect reinforcement bars and mesh, to measure their cover depth and to determine the bar diameter. The TC-100 offer simply one of the most convenient ways to inspect your concrete structures.
  • Detection of rebar and other metal building elements (such as steel pipes) and their orientation
  • Easy and accurate measurement of concrete cover depth and rebar diameter
  • Self correction function for the influence of neighbouring bars
  • Large LCD display with backlight
  • Optical as well as acoustic position signals
  • RS-232 output and data memory
  • Metric or imperial (mm/inch) setting



  • Acceptance inspection of cover after formwork is removed
  • Locate rebar’s to avoid them when drilling holes
  • Provides essential data (location, cover, diameter of rebars) for strength calculations of reinforced concrete structures
  • Measuring concrete cover depth
  • Quality assurance in mass production of prefabricated concrete elements
