Description
Overview
GAOTek Flaw Detector with 32 Flaw Detect Channel (Low-Power) is designed free to set and store a variety of flaw detection technology and standards which operates in the speed range from 400 m/s-20000 m/s. This high-performance instrument can work continuously for more than 20 hours. It provides adjustable amplitude and pulse width suitable for the detection of different materials and depth of the defects of the workpiece .It is widely used in rail transport, boilers, metal processing industry, steel, machinery, pressure vessels aerospace, military, automobiles, shipbuilding, metallurgy, nuclear power and university laboratories.
