I. Application
1. Locate the position of steel bars in a concrete structure and identify their reinforcement drawing.
2. Estimate the diameter of the steel bars and the thickness of the protective layer.
3. Measure the thickness of the protective layer when the steel bar diameter is known.
4. Measure the thickness of the protective layer on a specific surface with grid indication.
5. Measure the thickness of the protective layer along a certain line, indicating the steel bars at the cross-section.
6. The probe is equipped with a self-correcting function for improved accuracy.
7. Data can be saved and retrieved for future reference.
8. Data transfer is supported via USB or other compatible interfaces.
II. Description
