Description
Overview
GAOTek 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 structures, boiler pressure vessels and other fields. It is a necessary professional precision instrument for defect detection, quality control, in-service safety monitoring and life evaluation in railway, shipbuilding, metallurgy, chemical industry, petroleum and other industries.
