WSD-2A Digital Sonic Instrument

WSD-3 system is developed on the basis of years’ research and integrated with the latest technologies, such as 14bit A/D, surface mount technology and multi-layer PCB, etc. It is portable and applys for various complicated conditions in engineer prospection.


It applys for material and structure inspecting, with sonic or ultrasonic wave, such as on non-ferrous material of concrete, rock, rock core sample, ceramic, graphite, without damaging the measured object. Or on intensity detecting of concrete components, on inner fault detecting of the structure; fissure inspecting, complex detecting on quality and depth of the damaged section of the object, structure thickness, pier foundation quality inspecting and parameter check of elastic-material mechanics, etc.

Specific for
a). Perform penetration test on rock, rock core sample, concrete and other non-ferrous materials.
b). Inspecting pier foundation, or intensity, shallow fissure, deep fissure, density, homogeneity of the object, etc.
c). On engineering borehole survey, transmitting once in a single borehole can receive signal from several directions, or performing cross borehole survey.
d). Integrity test on pier through hammering.
