Intelligent crack depth gauge is used for quantitative detection of concrete crack depth values. The equipment mainly consists of a control host, transmitting receiving probes, and connecting cables.

Testing method: Single point rapid measurement or multi-point precise measurement.

Depth measurement principle: Single point rapid measurement adopts the principle of first wave inversion, and evaluates the geometric relationship between acoustic diffraction angle and crack depth; The multi-point precise measurement method adopts multi-point sound time/distance measurement, which is statistically evaluated according to technical specifications.

Compliant with specifications: Technical Specification for Ultrasonic Testing of Concrete Defects CECS21-2000.
