Proceq Profometer 4 Manual -

PM8000

The Proceq Profometer series has been a cornerstone of non-destructive concrete testing for over 40 years. While the newer and PM600 series now feature advanced touchscreens and wireless connectivity, the classic Profometer units—including the Profometer 4 and 5—remain widely used for their rugged reliability in locating rebar and measuring concrete cover. Core Functionality & Operation

  • Train operators on calibration and interpretation of results.
  • Combine Profometer results with complementary methods (GPR, chain drag, half-cell potential) for comprehensive assessment.
  • Keep a calibration and maintenance log.
  • For critical measurements, perform spot destructive checks.

  2. Search Probes (typically the 4-inch or 9-inch probe).
  3. Charger/Power Supply.
  4. Spacer Block (for depth verification).
  5. Carrying Strap and Transport Case.
  • Clean the Surface: While the Profometer 4 is robust, rough or uneven surfaces can create air gaps between the probe and the concrete, leading to overestimations of cover depth. Use the spacer ring on rough surfaces if possible.
  • Avoid Interference: Remove large metal objects from the immediate work area (e.g., steel-toed boots, metal shovels) before scanning. Do not use the device near strong electromagnetic fields (high-voltage cables).
  • Lift-Off Distance: Be aware of the "blind zone." If the rebar is extremely shallow (e.g., <5mm), the sensor might saturate. Always use the spacer ring for shallow bars.
  • Moisture: Wet concrete can slightly affect magnetic field readings. If scanning saturated concrete, allow the unit to acclimatize and take multiple readings to establish an average.
