Description
Overview
GAOTek Portable Industrial Ultrasonic Flaw Detection Equipment is a collection of portable and fully digital ultrasonic flaw detector. The two models in the series–high version and low version–all have the capacity to detect, localize and evaluate various defects in metals with rapidity and precision. Particularly, it is highly effective in the detection of welds, cracks, inclusions, and metal porosity in a non-destructive manner that is suitable for laboratory or project site environments. The detector’s wide variety of applications can be highly useful for defect detection and quality control in manufacturing, steel metallurgy, metal processing and chemical engineering, among other industries. Moreover, it can also be widely used for in-service safety inspections and live assessments in aircraft, railway and traffic industries, as well as boiler and pressure vessels.
