Essential in congested areas where closely spaced bars might otherwise result in an artificially shallow cover reading. 4. Maintenance and Calibration
When the visual indicator (rifle scope or LED) is centered, the probe is directly over the rebar.
Ideal for long-distance measurements across a single layer of rebars. proceq profometer 4 manual
The is a classic eddy current pulse induction instrument designed for the non-destructive location of reinforcing bars (rebar) and the measurement of concrete cover depth. While succeeded by advanced digital units like the Profometer PM-8000 or PM-600 , the Profometer 4 remains a staple for on-site quality control due to its reliability. 1. Core Measurement Principles
While the basic "Spot" mode is standard, the Profometer line supports specialized scans: Essential in congested areas where closely spaced bars
Hold the probe in the air, away from any metal objects, and press the Zero button. This calibrates the device to the current environmental conditions.
Used to map a grid of reinforcement over a larger rectangular area, producing a "heat map" of cover depths. Ideal for long-distance measurements across a single layer
The center line of the probe indicates the precise location of the rebar. 2. Essential Operating Steps
