Abstract:
1. A non-destructive evaluation system for testing wood products, comprising: a first integrally formed handheld measuring probe having a body that includes a shaft defining a first impact surface, a spike fixedly coupled to one end of the shaft, a transducer in contact with the spike for detecting a stress wave imparted thereto and outputting a signal indicating the presence of a stress wave, and a handle slideably coupled to the shaft; a second integrally formed handheld measuring probe having a body that includes a shaft, a spike fixedly coupled to the shaft, a transducer in contact with the spike for detecting a stress wave and outputting a signal indicating the presence of a stress wave, and a handle slideably coupled to the shaft; and an electronic unit including a timing device, the electronic unit coupled in electrical communication with the transducer of the first measuring probe and the transducer of the second measuring probe for receiving the outputted signals therefrom; wherein the electronic unit determines the travel time of the stress wave from the transducer of the first probe to the transducer of the second probe.
