Proceq Profometer 4 Manual May 2026

The device can store up to 100,000 measurement points.

| Mode | Use | |------|-----| | Cover Meter | Measure concrete cover depth over rebar | | Bar Locator | Find position of rebars (with audible tone) | | Scan | Continuous logging along a line | | Data Transfer | Export readings via USB or Bluetooth (optional) |

This mode is used to find the position and direction of the rebar.

  • Marking: Once the bar is found, rotate the probe 90 degrees. The signal will drop and then peak again when you cross the bar perpendicular to the first direction. This helps map the grid.
  • Press the ON button. The unit will perform a self-test. The display will show the software version briefly before entering measurement mode.


    Press the 'Save' icon. The manual recommends naming files by project ID and grid label (e.g., "BridgePier_Grid_A1").

    If the cover depth is known (or estimated), the Profometer 4 can estimate the diameter of the rebar.

    The rain had stopped, but the half-built bridge groaned in the wet wind. Elena wiped a smear of muddy water off the screen of her Proceq Profometer 4. The battery was at 12%. The manual was back in the truck, buried under a week’s worth of coffee cups and grouting samples.

    “Damn it,” she whispered.

    The concrete deck in front of her looked solid. But the client’s survey had shown shadows—anomalies in the rebar network two inches below the surface. If the rebar spacing was off by more than a centimeter, the entire span would fail the load test. And failure meant firing squad of investors.

    She tapped the Profometer’s hard-worn membrane keypad. The device hummed, its small wheel scanner trembling in her other hand. She’d used this tool a hundred times before—for depth checks, for corrosion potential—but never in the dark, alone, with a storm rolling back in.

    On the screen, a jagged red line spiked. Then flatlined. Then spiked again. The device can store up to 100,000 measurement points

    Wrong, she thought. That pattern makes no sense.

    She needed the manual. Not the quick-start card, not the YouTube tutorial from 2019. She needed the original Proceq Profometer 4 manual—the 147-page PDF with the cross-section diagrams and the cryptic warning on page 62 about “ferromagnetic interference in saturated aggregates.”

    Her phone had no signal. The truck was 400 meters away, through a construction site that was now a swamp.

    Elena made a choice. She sat on a wet concrete block, pulled up the offline PDF she’d foolishly downloaded months ago (thank you, past self), and searched “spike-flatline-spike.” The answer was buried in Section 4.3: “Ringing effect—caused by closely spaced bars touching at a hairline crack. Measure perpendicular to suspected contact point.”

    She shifted the scanner 90 degrees. The trace smoothed. The rebar was perfect.

    The Profometer beeped. Battery 3%.

    Elena smiled. The bridge would stand. And somewhere in Switzerland, the ghost of Proceq’s engineering team nodded in approval.

    She never left the manual behind again.
