Ultrasonic Product Digital Ultrasonic Flaw Detector Ew-620 for Nondestructive Testing

Ultrasonic product Digital ultrasonic flaw detector EW-620 

for Nondestructive testing

EW-620 digital ultrasonic flaw detector can quickly and easily, without injury, 
accurate workpiece within a variety of defects such as cracks, weld, porosity,
sand holes, inclusions, folding detection, localization, assessment and diagnosis, widely used in electric power, petrochemical, boiler, pressure vessel, steel structure, military, aerospace, railway transportation, automobile, machinery and other fields. It is an essential instrument for nondestructive testing.

High precision quantitative and positioning, meet the close and distant inspection requirements;
The near field zone is small, to meet the testing requirements of small diameter, thin wall tube;
The automatic calibration of automatic calibration: one button, the operation is very convenient, the automatic test probe of the "zero", "K", "front" and "sonic material";
The automatic display of the defect echo location (depth D, level of P, s, dB, distance amplitude, 
equivalent aperture phi value);
The freedom to switch three kinds of scales (depth D, level of P, s);
The automatic gain, echo envelope, peak memory function in improving the inspection efficiency;
The automatic detection process can be recorded and dynamic playback; (unlimited)
