Rebar location is a central activity for anyone involved in on-site testing of reinforced structures. Locating rebars is a necessity when drilling, cutting coring as well as a preliminary operation required for most other non-destructive investigations. Other typical applications include conformity check of new buildings, investigations on unknown structures and corrosion analysis. The eddy current pulse induction principle is the only imaging technology not influenced by concrete composition and humidity, which leads to a high cover accuracy under every scenario. Since the early 1970s, Proceq has been addressing those different needs through a continuous development effort of rebar locators and concrete cover meters, offering the best features needed for any specific application.
