Penetration Coating Mode 2.5-25mm Through 2mm Coating UT Thickness Meter TG-8812D
1. Overview
Ultrasonic thickness gauge is a kind of high-precision thickness gauge which uses ultrasonic measurement principle, adopts high-speed processor and high integrated chip design to realize portable, nondestructive, fast and accurate measurement of thickness and sound velocity of various materials. It is suitable for measuring the thickness of various materials, such as steel, metal, glass, ABS, plastics, PVC, ductile iron, etc., which can be transmitted by ultrasonic wave at a constant speed in its back.
