AUMU “Scanner” Portable, multichannel flawdetector

Portable multichannel fl aw detector – thickness gauge AUMU “Scanner” is the basis for establishment of small areas of automatic high-speed ultrasonic inspection in production flow for diff erent products. Depending on inspection purpose the detector may have up to 9 independent channels.

Nondestructive inspection and thickness gauging of weld joints and base metal of products is performed at a speed of up to 2 m/s.
