T-4000 Precision Ultrasonic Thickness Gauge

Introduction
With the help of latest technology, the T-4000 precision ultrasonic thickness gauge realizes high-precision thickness measurement and data storage. This digital measuring instrument is able to read as small as 0.254mm. Its resolution can be adjusted to 0.00254mm. This dynamic thickness meter is usually applied to measure metallic and nonmetallic materials, like steel, aluminium, titanium, plastics, ceramics, glass and other good ultrasonic conductors with parallel top and bottom surfaces. After simply calibrating the known sound velocity or thickness, the ultrasonic thickness gauge is capable of precisely show the reading in metric or imperial system.
