Olympus 35rdc





35RDC Composite Damage Checker
The handheld 35RDC is a simple Go/No-Go ultrasonic instrument designed to detect subsurface defects caused by impact damage on solid laminate aircraft composite structures. The 35RDC features a backlit LCD that displays the word GOOD if no subsurface damage is found or the word BAD when it detects subsurface damage. It uses an ultrasonic transducer that can be placed or scanned on the area of composite material suspected of having impact damage. Weighing only 0.24 Kg (8.5 oz.) and featuring a simplified keypad, this rugged ultrasonic instrument is easy to operate and requires minimal training.
