This equipment can inspect various workpieces for air bubbles, peeling spots, defects, and crimping failures inside.

With a Yamaha ultrasonic amplifier installed, inspection without touching the workpiece in the air is realized. Air bubbles and peeling spots difficult to be detected by X-ray inspection can be vividly detected. A standalone/general-purpose type, and a full-auto/conveyor type are available.
