Description

Product Introduction:

Based on the ultrasonic measurement principle, this instrument is suitable for measuring the thickness of materials that allow ultrasonic waves to propagate at a constant speed and reflect from their back side. It enables precise measurements of plates and machined components, and—more importantly—can be used to monitor pipelines and pressure vessels in industrial equipment, assessing the degree of wall thinning caused by corrosion during service. The device finds applications across diverse sectors, including petroleum, chemical processing, metallurgy, shipbuilding, aerospace, and more. It is well suited for measuring the thickness of metals (such as steel, cast iron, aluminum, copper, etc.), plastics, ceramics, glass, fiberglass, and other materials that are good ultrasonic conductors. Principle of operation:

The principle of ultrasonic thickness measurement is similar to that of optical wave measurement. An ultrasonic pulse emitted by the transducer travels into the test object, and upon reaching a material interface, it is reflected back to the transducer. By precisely measuring the time it takes for the ultrasonic wave to propagate through the material, the thickness of the material being measured can be determined.

Product Features:

● For composite and unknown materials with known thickness, accurately determine the sound velocity through inverse analysis.

● Set upper and lower tolerance limits; an automatic alarm will sound if the limits are exceeded.

● Status indication function.

● Equipped with instrument calibration functionality;

● Adjustable sound speed;

● Can store 2,000 data records;

● Features a coupling status indicator;

● Features a high-brightness LED backlight for convenient use in low-light environments;

● Equipped with a remaining battery‑level indicator, it can display the battery’s remaining charge.

● Features power-saving functions such as automatic sleep and automatic shutdown;

● Compact, portable, and highly stable; suitable for harsh operating environments, with resistance to vibration, shock, and electromagnetic interference.

● Metric and imperial units are selectable.
