A1221 ANCHOR
Ultrasonic Pulse-echo Flaw Detectors
Ultrasonic Anchor Bolt Testing
An ultrasonic low-frequency tester for in-situ quality assessment of concrete anchors, solid rebars and reinforcement.
Product Description
A1221 ANCHOR is an ultrasonic instrument for in-situ evaluation of embedded metallic elements by means of low-frequency ultrasonic waves.
Application
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
