A1221 ANCHOR is an ultrasonic instrument for in-situ evaluation of embedded metallic elements by means of low-frequency ultrasonic waves.

The main application field of A1221 ANCHOR is the non-destructive testing of anchor bolts and similar structural elements.

Following evaluations can be performed by placing ultrasonic transducer on the free outer end of the bolt:

  • Detection of anchor breaks
  • Residual length/fraction assessment
  • Adhesion quality assessment

Application features:
