Ultrasonic flaw detectorDetailed product description：

The UTL350 is a newly developed portable, digital ultrasonic flaw detector that can quickly, conveniently, without damage, and accurately detect, locate, evaluate, and diagnose various internal defects (cracks, inclusions, pores, etc.) in workpieces.
It can be used in both laboratories and engineering sites. This instrument can be widely used in manufacturing, steel metallurgy, metal processing industry, chemical industry and other fields that require defect detection and quality control. It is also widely used in in-service safety inspection and life assessment in aerospace, railway transportation, boiler pressure vessel and other fields.

UTL350 ultrasonic flaw detector features:
1. Full Chinese display, master-slave menu, and designed with shortcut buttons and digital shuttle wheels, easy to operate and technologically advanced.
