China Depth Measurement Instrument

I. According to:
Technique Regulation of Concrete Defect Detection with Ultrasonic CECS21: 2000
II. Depth measurement principle
When vibration energy transmit through the concrete and pass the crack, the vibrate energy will be diffracted at the point of the crack, whose diffraction angle have geometrical relationship with the crack depth. DJCS-05 crack depth measurement instrument adopt this geometrical between the diffraction angle and depth to realize high precision depth measurement.
