Crack depth meter
- Suitable for measurement on both ferromagnetic and non-ferromagnetic materials (e.g., stainless steel, aluminum alloys).
- Wide measuring range from 0.2 to 100.0 mm.
- Minimal influence of material electromagnetic properties on measurement results.
- Equipped with various probe designs for inspecting products of irregular shapes.
- Mobile spring-loaded contact electrodes on the probe enable measurements on curved surfaces.
- Suitable for use in field, workshop, and laboratory conditions.
Stages of crack depth measuring
- Setting the “0” – measure on an undamaged area of the object.
- Measuring crack depth – position the contact electrodes on opposite sides of the crack, and the depth measurement in mm will be displayed on the screen.
Requirements for control objects
- Surface roughness of 40 Rz (10 Ra) or less.
- Stable electrical contact with the probe electrodes.
