Defect Assessment Blocks

Defect Assessment calibration blocks from Eclipse Scientific contain a variety of targets and geometries specifically designed for calibrating ultrasonic equipment to be used in defect sizing applications .

If you do not see the calibration block you require listed below contact Eclipse for one to be custom-made.

  • All calibration blocks are precision machined and manufactured from ultrasonically pre-inspected steel
  • Custom calibration blocks available with targets, geometry, and type of material selection based on application requirements
  • All blocks finished with nickel plating unless otherwise specified
  • Additional targets may be incorporated if required. Optional targets include radial or square bottom holes, tapered or V-shaped grooves, saw cuts, side drilled holes, machined notches, or EDM targets

Thin Wall Block

The ETW block is an all-in-one calibration block that incorporates 31 targets, providing ample targets for transducer calibration and training in defect sizing. The ETW block can be used for opposite wall defect evaluation and training, normal beam transducer calibration, and many more applications.

  • Side Drilled Holes
  • Flat Bottom Holes
  • Step wedge region (5 known thicknesses)
  • Notches

Pipe Calibration Blocks

Custom made calibration blocks for pipe applications. OD and ID targets precision EDM to specific code case to suite your specific pipe needs.
