This series of digital ultrasonic thickness gauges with A-scan and B-scan function helps the user make more accurate thickness measurement. The thru-coating function available is designed for thickness testing without removing the paint. This instrument is widely applies for measuring the thickness of metal materials, pipes, pressure vessels, sheet metals (steel, aluminum), plastic, steel pipes, PVC pipes, glass and other materials.

Tips: Couplant of ultrasonic thickness gauge

In order to improve the sound energy transmission between the probe of ultrasonic thickness gauge and the workpiece, a thin layer of liquid applied between the probe and the detection surface is called a couplant.

When there is a layer of air between the probe of ultrasonic thickness gauge and the workpiece, the reflectivity of the ultrasonic wave is almost 100%. Even a thin layer of air can prevent the ultrasonic wave from entering the workpiece. Therefore, it is very important to remove the air between the probe and the workpiece. Coupling agent can fill the air gap between the probe and the workpiece, so that ultrasound can be transmitted to the workpiece, which is the main purpose of using the couplant. In addition, the couplant also has lubrication effect, which can reduce the friction between the probe of ultrasonic thickness gauge and the workpiece, prevent the workpiece surface from wearing the probe, and make the probe easy to move.

According to the surface condition and acoustic impedance of the workpiece to be tested, the coupling agents without bubbles and suitable viscosity should be selected, such as glycerin, oil, silica gel, water glass and paste, high temperature coupling agent, etc. If the surface of the workpiece is rough, the thicker coupling agent should be chosen. The coupling agents specially used for thickness measurement can also be used. In practical use, it is necessary to keep the coupling agent clean, not to make it stained, or it will affect the accuracy of measurement of ultrasonic thickness gauge.
