COBEP0701 Weld crack detector, as a new testing method based on the electromagnetic theory, is the breakthrough of COBE engineers after years of industrial and laboratory studies. It solves the complex ultrasonic processing problem with its fast testing processing and no requirement of surface clearness.
With high sensitivity and high-precision detecting and the combination of our own exclusive intelligent probes, it’s to improve your testing efficiency and reduces your inspection costs.
Obtained the national science and technology fund of technology-based SMEs in technology innovation fund in 2008
Instruments passed the European standard :
EN1711-2000 Eddy Current impedance plane analysis of the weld testing
★Quick weld and workpiece surface crack detection
★No need to polish the weld, remove the surface corrosion and clean the metallic surface
★The largest lift-off height of up to 3 mm
★detected with high sensitivity: 0.05mm (smooth surface)
★real-time display equivalent defect size
★simple / quick to grasp
★Built-in battery, small size, easy to carry to the job with the site altitude
Mainly used for welding crack testing
