Product Description

Ultrasonic Flaw Detector Novotest UD3701

Ultrasonic Flaw Detector NOVOTEST UD3701 is designed to detect defects, such as discontinuity and heterogeneity in objects, weld joints quality, to measure the depth and position of flaws, thickness measurements, measurements of velocity and attenuation of ultrasonic waves for different materials.
Ultrasonic Flaw Detector NOVOTEST UD3701 has large 7 inch touch screen display and powerful, lightweight, portable and ergonomic impact-resistant metal casing, and is the best choice for expert ultrasonic testing. Ultrasonic Flaw Detector NOVOTEST UD3701 allows user to measure the thickness of products with hight accuracy, the signal can be viewed in the form of A-scan and B-scans and has all the features of the full testing documentation.
