Special test block KO28-2
For crack depth meters
Serves as a critical tool to assess the functionality of the ET-28 - Crack depth meter electro potential. This specialized block is designed to ensure accurate and reliable crack measurements in various industrial applications.
Key features
- The KO28-2 sample features five simulated cracks of 2, 5, 10, 20, and 30 millimeters.
- Constructed from high-quality structural carbon steel, the sample ensures durability and longevity, providing consistent performance over time.
Operational advantages
Verification Procedure: Before each usage, the device should be tested on a control sample to ensure accurate measurements.
Crack depth measurement process:
- Setting the “0”: measuring a flawless location on the object to establish the baseline.
- Measuring crack depth: position the contact electrodes on opposite sides of the crack, and the measurement result in millimeters will be displayed on the screen.
Object requirements:
- Control objects should exhibit surface roughness below or equal to 40 Rz (10 Ra)
- Stable electric contact with the sensor electrodes.
Technical specifications
- Crack Depth: 2, 5, 10, 20, 30 mm
- Crack Width: 0.2 mm
- Sample Dimensions: 250 x 60 x 40 mm
- Weight: 5 k
