Datalogger
- highly precise, extreme low-noise USB data loggers
- Records saved in CSV format
- loggers are mounted inside our potentiostat

Camera System for visual evaluation
- Camera zooms into inspected area.
- Damage is to be recognized as a circle, which is
divided into segments at an even angle (picture: 12
segments, 30° angle) - For each segment the depth of disbonding is
measured in mm from the bore hole to the surface
defect.
