Rebar Location
Cover Meter and Ground Penetrating Radar (GPR) are suitable for locating rebars and reinforcement in concrete.
An Eddy Current Cover Meter like the Profoscope or Profometer performs best for cover measurement with a precision of 1mm within the first 40 mm cover, however it has a limitation on penetration depth of up to 150 mm.
It is highly recommended to use GPR for locating multi-layer reinforcement such as post tensioning. GPR can scan up to 700 mm deep in concrete.
Profoscope
The Profoscope is a cover meter and rebar detector. It uses pulsed eddy current to detect and measure the depth and estimate the diameter or reinforcing steel (rebar) within concrete.
Engineers use this for quality assurance to determine if the minimum concrete cover is achieved.

Profometer
The Profometer is an advanced equipment for cover measurement and rebar location. It uses the same principle as Profoscope – pulsed eddy current to detect and measure rebars within concrete.
Adding to the precise depth measurement is powerful data logging and presentation functions that allow you to visualise the rebars and concrete cover. It provides: -
- Detailed cover measurement across a line scan
- Spacing of the rebars
- Multiple line scans on one file
- Area scan with detailed cover measurement
The Profometer provides better data presentation to engineers for structural assessment and quality assurance check. Its also the right choice with congested, or complex rebar layouts.
Ground Penetrating Radar
Ground Penetrating Radar systems use a radar signal sent into the concrete to produce an image of rebar layout.
Ideal for scanning structures with unconventional reinforcing or multiple layers.
Cover depth measurement with GPR is less precise than with a cover meter, with an uncertainty of as much as 10mm.
Radar scanning is ideal for locating steel and other embedments before cutting / coring, or to provide a holistic view of concrete embedments.
