Internal rechargeable battery packs or high-quality AA batteries (depending on the specific sub-variant configuration).
The Profometer 4 can be upgraded to assess the corrosion likelihood of reinforcing steel using the half-cell potential method. This technique measures the electrochemical potential between a reference electrode and the embedded steel. This measurement helps identify areas with a higher probability of active corrosion.
: Dedicated dials for zeroing, diameter selection, and depth range adjustments.
Never wrap the probe cable tightly. Looping it loosely prevents internal wire breaks. Need the Full Manual? proceq profometer 4 manual
Move the probe slowly across the concrete surface in a grid pattern.
: Confirm the device was "zeroed" away from all metallic objects (including jewelry) before starting measurements to calibrate signal strength.

A: The half-cell probe typically lasts 5-7 years. The manual includes a "Check" function. If the potential drifts more than 20 mV when measured against a known standard, replace it.
Use the diameter settings to adjust the reading to match known rebar sizes. 4. Maintenance and Troubleshooting
: Provides an estimated bar size, which is critical for structural assessments where original plans are missing. Operational Features Eddy Current Pulse Induction Looping it loosely prevents internal wire breaks
Check Proceq’s website (now part of Screening Eagle Technologies) for updates. The manual explains how to install a .fw file via USB.
: Include high-level metrics if multiple points were scanned: Mean Cover : Average depth across the tested area.
: When the probe passes over a conductive material (such as a steel rebar), eddy currents are induced within the steel. These currents create a secondary magnetic field that opposes and distorts the primary field.
