Locate an isolated rebar where no parallel bars interfere with the signal.
Ideal for long-distance measurements across a single layer of rebars.
Determines the thickness of the concrete protecting the steel.
: The modern successors integrate with iPads via Bluetooth for high-resolution 3D visualizations and cloud reporting.
Move the probe back and forth to find the highest signal strength, which signifies the center of the bar. 3.2 Measuring Concrete Cover proceq profometer 4 manual
Place the search head on the calibration test block to confirm the unit reads the block’s specified depth within the manual's allowable tolerance ( ±1plus or minus 1 Step 2: Locating Reinforcing Bars
This comprehensive guide serves as an operational manual, covering the core technical specifications, step-by-step operation, calibration procedures, and troubleshooting methods for the Profometer 4. 1. Technical Specifications and System Component Overview
This is usually caused by low battery voltage or proximity to high-voltage power lines. Replace the batteries and move away from strong electromagnetic fields.
The connection between the search head and the unit is the most common point of failure. Avoid tight kinks or pulling on the wire. Locate an isolated rebar where no parallel bars
Estimates the size of the rebar when the cover depth is known. Core Components

The signal intensity increases as the probe approaches a rebar. The rebar is located directly beneath the center of the probe when the display shows the minimum cover depth (or maximum analog needle deflection) and the audio signal reaches its highest pitch. Measuring Concrete Cover
The Proceq Profometer 4 is a legacy concrete testing instrument. It is widely recognized for its reliability in locating reinforcing bars (rebars) and measuring concrete cover depth. This guide provides a comprehensive overview of its operations, calibration, and scanning methodologies based on the official manual guidelines. 1. Introduction to the Profometer 4 : The modern successors integrate with iPads via
Eddy-current bar locators are highly sensitive to external variables. Operators must account for the following factors in the field:
If the diameter is unknown, you must use a localized breakout, a specialized correction method, or a modern dual-measurement probe to estimate the diameter first. Setting an incorrect diameter will result in inaccurate cover depth readings. Step 3: Locating the Rebar Center Line Place the probe flat against the concrete surface.
Set the on the instrument to match the known nominal diameter of the reinforcement bar.
Ensure the cable is securely fastened to both the probe and the indicating unit.
