The RD3 (Rapid Damage Detection Device) is a hand held, low cost non-destructive inspection instrument that can be used to detect voids, degradation, and delaminations in composite structures. No more tapping with a coin in a noisy environment for questionable results. The RD3, also known as the Electronic Digital Tap Hammer, supplements the subjective tonal discrimination of the operator with a quantitative, objective numeric readout that can be correlated to delaminations in the structure. The unit consists of a lightweight hammer containing an accelerometer, which is connected by flexible cable to components and a liquid crystal display.

With its low cost, quantitative and recordable readout and ease of use, the RD3 will prove invaluable and indispensable to routine non-destructive examinations.
