Buzz-o-sonic is a professional system for measuring the dynamic elastic and damping properties of materials, using the impulse excitation technique (ping test). It is the most cost effective and flexible instrument available. According to independent research at Oak Ridge National Laboratories, it is also one of the most precise. Custom designed systems for QA/QC, high temperature measurements, vacuum, and other applications are available.
Bars of uniform cross-section and discs can be tested as per ASTM E1876/C1259
