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
Move the probe slowly across the concrete surface. The signal strength will increase as you approach a bar. proceq profometer 4 manual
The Profometer 4 operates on the . A coil in the probe is energized by a current pulse, creating a magnetic field. When this field encounters a metallic object like a rebar, it induces eddy currents, which in turn generate a secondary magnetic field. Precision: It typically offers an accuracy of The is a classic eddy current pulse induction
If you "chase" the signal up and down and it remains consistent, you are following the length of the rebar. 3. Advanced Measuring Modes Core Measurement Principles Move the probe slowly across
