Digital ultrasonic flaw detector

The digital ultrasonic flaw detector can be fast, convenient, and non-destructiveDetecting, locating, evaluating, and diagnosing various internal defects such as cracks, welds, pores, sand holes, inclusions, folds, etc. in workpieces, widely used in fields such as power, petrochemicals, boiler pressure vessels, steel structures, aerospace, railway transportation, automobiles, and machinery. It is an essential instrument for non-destructive testing.

Performance characteristics:

High precision quantification and positioning meet the requirements of both near and far distance testing. The automatic gain, echo envelope, and peak memory functions have improved the efficiency of flaw detection.260000 color true color screen with ultra-high brightness display, adjustable brightness, suitable for working environments with strong and weak light. DAC sound and light alarm, screen freezing and thawing, clock display, sleep mode, and screensaver.
