Sonatest Masterscan 700M Digital Ultrasonic Flaw Detector

Description

Sonatest Masterscan 700M Digital Ultrasonic Flaw Detector – Professional Portable UT Inspection and Material Testing System

The Sonatest Masterscan 700M Digital Ultrasonic Flaw Detector is a high-performance narrowband ultrasonic testing instrument designed for professional non-destructive testing. It combines a full VGA display, powerful 100–450 V spike and square-wave pulser, advanced defect-sizing functions, and a wide measurement range for demanding inspection applications.

The Masterscan 700M is designed for weld inspection, corrosion detection, composite inspection, bond testing, forgings, castings, power-generation applications, and general ultrasonic testing. Its modular software architecture allows additional inspection functions to be added or upgraded in the field.
