摘要：
A method and apparatus for measuring the quality of live, standing timber employs deep-set spike probes angled to create a longitudinal compression wave. Alignment tools and isolation of the probes provide an improved signal, automated detection of probe separation and amplitude-independent pulse discrimination process ensure higher reliability and repeatability of the measurements, and wireless operation provides operational efficiencies.
