1. Introduction
This instrument is a portable industrial digital ultrasonic flaw detector that can detect, locate, evaluate and diagnose various defects (cracks, inclusions, pores, etc.) in the workpiece quickly, conveniently, without damage, and accurately. It can be used both in the laboratory and on the engineering site. This instrument can be widely used in manufacturing, iron and steel metallurgy, metal processing, chemical industry and other fields that require defect detection and quality control. It is also widely used in online safety inspection and Life assessment in the fields of aerospace, railway transportation, boilers and pressure vessels, etc.
