I. Specification NOVOTEST UD4701PA Ultrasonic Vulnerability Detector

NOVOTEST UD4701PA ultrasonic vulnerability detector
  • The NOVOTEST UD4701PA ultrasonic flaw tester can be used both with a standard 1-channel probe and with a PA 16-channel probe. Using the SAFT method, the device allows to obtain high-resolution scanned images. high and high quality. Using a replaceable prism, allows to avoid probe wear and to inspect any curved surfaces.
  • Based on innovative technologies, the NOVOTEST UD4701PA ultrasonic vulnerability detector is lightweight (1.5 kg) and includes functions such as A, B, C, D, S, L-scan, TOFD, DAC , DGS, AFS, AWS, automatic correction of ultrasonic velocity, reconstruction mode of weld geometry and other.
  • Calibration blocks are made with grooves (anglers) made of the same materials (steel, stainless steel, aluminum and others) as those under test, where the geometry (thickness) and surface radius of the reference sample) having the same characteristics as the item under test.
