Description

Overview

GAOTek Ultra Flaw Detector Concrete is a new generation thickness gauge, breakthrough technology provides a thickness gauge with better performance for the same budget. It greatly improves the performance of previous ultrasonic thickness gauges and has better measurement stability and repeatability. It is widely used for wall thickness measurement of pipelines, pressure vessels and storage tanks in petrochemical, electric power, ships and manufacturing industries.

 

Features

  • E Economical digital gauge with A-scan snapshot feature
  • Breakthrough zero-crossing measurement technology for accuracy
  • Coating penetration function; zero-free calibration; high stability
  • Zero drift; unaffected by probe pressure, coupling layer, or dust
  • Adjustable gain; dynamic alarm color; difference/reduction rate feature
  • Maximum/Minimum Capture: simultaneous display of values on screen
