Introduction The Proceq Profometer 4 is a widely used non-destructive testing (NDT) instrument designed to locate and estimate the depth of steel reinforcement in concrete structures. As bridge decks, parking garages, building slabs, and other reinforced concrete elements age, accurate knowledge of rebar position and cover thickness becomes critical for assessing durability, planning repairs, and ensuring structural safety. This essay describes the Profometer 4’s capabilities, typical applications and workflow, advantages and limitations, and its broader impact on structural inspection practice.
Conclusion The Proceq Profometer 4 is a practical, field-ready electromagnetic cover meter that contributes valuable information to concrete inspection and maintenance workflows. While it cannot replace complementary NDT techniques for complex investigations, its portability, speed, and non-destructive operation make it an essential instrument for locating reinforcement, estimating cover, and preventing damage during construction activities. Operators should be mindful of the device’s limitations, perform proper calibration, and combine Profometer data with other assessments to achieve robust structural evaluations.
