HA-701W | Ultrasonic Flaw Detection System
[Measurement Equipment [ Other measurement equipment ]]


  • Displays A-mode, B-mode and C-mode image on the screen altogether and enables easy detection of flaw in the object.
  • Different frequency of ultrasonic concave probes can be selected suite to the object material, size and type of flaw.

flaw detecting image

  • Applicable to internal flaw detection of semiconductor, ceramics, resin, metal, cast metal
  • Different type of flaw, such as cracks, voids or bonding defect
  • Ultrasonic travels through non-transparent material and enables non-destructive observation.

Image mode

A-scope, B-scope, C-scope
three scope image

●A-scope (A-mode)
The basic wave pattern indication of flaw detection.  
It indicates reflected echo intensity (wave patterns) received by a probe and the transit time of ultrasound (distance) on the rectangular coordinates.

●B-scope (B-mode)
Tomography, or cross-sectional profile, through one vertical slice of a sample.  It indicates the location of a probe and the transit time of ultrasound (distance) on the rectangular coordinates. 
 The intensity of echo in the A-scope wave pattern is modulated by brightness or color, and the brightness (or color) of a dot on the coordinates is proportional to the intensity of the echo.
The existence, distribution and location is determined intuitively.

●C-scope (C-mode)
Tomography, or cross-sectional profile, through one horizontal slice of a sample.  The image of C-scope is similar to that of an optical microscope.  The echo intensity received at a fixed depth is modulated by intensity.  The distribution of flaws on the horizontal plane is more easily determined.
