Description
Overview
GAOTek detection 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. 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. It is widely used in aerospace, railway transportation, building steel structure, boiler pressure vessel and other fields.
