Proceq Profometer 4 Manual May 2026

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

Grid Mapping

: Mark the locations of several parallel bars, then repeat the process at a 90° angle to build a complete representation of the rebar grid. Modern Alternatives & Resources proceq profometer 4 manual

Locating Rebar:

Move the probe slowly over the concrete surface. The signal strength increases as you approach a bar. The precise location of the rebar is directly under the center of the probe when the signal reaches its peak. PM8000 The Proceq Profometer series has been a

The final chapters of the manual deal with longevity. Here are critical excerpts: Daily: Clean probe wheel with dry cloth

• Daily: Clean probe wheel with dry cloth.
• Monthly: Check calibration on provided reference bar (cover depth should read ±1mm).
• Yearly: Factory calibration recommended (contact Screening Eagle).

• Green ( > -200 mV): Low corrosion probability (10%)
• Yellow (-200 to -350 mV): Uncertain corrosion activity
• Red ( < -350 mV): High corrosion probability (>90%)

This is the most common use case. The manual breaks this into a 5-step procedure.
