WSD-2A Digital Sonic Instrument

Application:

Primarily applied for detecting concrete, rock and core sample, and nonmetallic material such as porcelain, graphite by sound or supersonic wave nondestructive detecting.

It can be used for intensity detection, intrinsic defect detection, fissure detection, interface quality and rupture thickness detection, equality detection, framework thickness detection, pile foundation inspection, sonic logging and material elastic parameter detection and other applications.
