Description
Overview
GAOTek High Precision Digital Portable Ultrasonic Flaw Detector can quickly, non-destructively and accurately detect various defects (cracks, inclusions, blowhole, etc.) inside the work piece. The product is unique in design, easy to operate and durable. It adopts all-Chinese true colour liquid crystal display. Different colour 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. 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.
