Rebar location needs to be fast and accurate. Profoscope has a unique real-time rebar-visualization allowing the contractor to actually “see” the location of the rebar beneath the concrete surface.

This is coupled with rebar-proximity indicators and optical and acoustical locating aids. These unique features combine to make the task of locating rebars a simple and efficient process, saving time and money for contractors and providing them with the information they need to do their job fast.

The Profoscope uses electromagnetic pulse induction technology to detect rebars. Coils in the probe are periodically charged by current pulses and thus generate a magnetic field. On the surface of any electrically conductive material which is in the magnetic field in opposite direction. The resulting change in voltage can be utilized for the measurement. The Profoscope uses different coil arrangements to generate several magnetic fields. Advanced signal processing allows:

• localization of a rebar
  
• localization of the mid-point between rebars
  
• determination of the cover
  
• estimation of the bar diameter
  
• determination of the orientation of a rebar

The Profoscope+ has the same features as the Profoscope, but also offers memory function to download, edit and present the data measured. Data exchange can be done easily by connecting the Profoscope+ directly to the USB-port of the PC or by reading out the integrated Micro SD memory card.
