Description
Overview
GAOTek ultrasonic flaw detector can quickly, non-destructively and accurately detect various defects (cracks, inclusions, blowhole etc.) inside the workpiece. The product is unique in design, easy to operate and durable. It adopts all-Â truecolor liquid crystal display. Different color schemes can be selected according to the environment. The brightness of liquid crystal can be adjusted under strong outdoor light. Master-slave menu design, with digital shuttle wheel, easy to operate, leading technology.
