Engineering Acoustic Instrument - GSY-1

Main Applications and Features

Mainly used for sonic and ultrasonic detection; it can be applied in Nondestructive Testing (NDT) of rock mass and concrete, census (general survey) and follow-up of construction quality, single-hole logging, cross-hole logging. Widely used in testing of strength, internal defects, cracks, joint surface quality and damaged layer thickness, pile foundation quality, sonic logging and parameters of material elasticity, etc.
