35RDC是一款简单的Go/No-Go（快速确定产品合格/不合格）的超声测厚仪，用于探测飞行器复合材料结构受到撞击而产生的近表层缺陷。这款测厚仪带有一个背光液晶显示屏（LCD），如果没有发现近表层损伤，显示屏上会显示GOOD（合格）字样；如果探测到了近表层损伤，显示屏上会显示BAD（不合格）字样。

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.Features
