Description
Overview
GAOTek portable industrial digital ultrasonic flaw detector 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. The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.
Features
- The core hardware is designed with ARM+FPGA,
- The software uses a highly reliable multitasking operating system
- Improves the function, portability, durability and reliability of the instrument.
- This instrument uses a master-slave menu and is designed with shortcut keys and a digital rotary knob.
- The instrument is light and portable and can be held with one hand.
