Description
Overview
GAOTek portable flaw detector can quickly, non-destructively and accurately detect various defects (cracks, inclusions, blowholes, etc.) inside the workpiece. The product is unique in design, easy to operate and durable. It adopts all-English true color liquid crystal display. Different color schemes can be selected according to the environment.
