The compact, lightweight PROFOMETER 5+ Rebar Detection System brings the power on non-destructive pulse-induction technology to the detection of rebars. Using the pulse induction measuring method enhances accuracy by making the instrument virtually insensitive to external interferences. In addition, a correction can be included for the effect of adjacent, parallel bars on diameter determination and concrete cover measurement. A second correction is for measurement of cover depth in congested bar arrangements. With the universal probe, not only can the instrument measure two concrete cover regions at the push of a button, but also the diameter determination can be performed without changing probes.
