major function
By using the "echo echo" technology, ultra-thin parts can be measured, with a minimum thickness (steel) of 0.15mm; On the other hand, high-precision thickness measurement can be achieved with a resolution of 0.001mm; It can also penetrate the surface coating thickness to measure the substrate thickness;
● Increase the function of measuring substrate thickness through penetrating coatings, with surface coatings less than 500um;
● Two types of measurements: the bottom wave echo mode satisfies the conventional measurement of thick workpieces; The echo echo mode satisfies high measurement accuracy for thin workpieces;
The probe is placed on the thickness gauge test block and automatically zeroed by pressing the button;
● Equipped with LED backlight display, convenient for use in low light environments;
● Equipped with sound speed calibration (reverse measurement of sound speed) or single point calibration function;
● Can set alarm and difference modes;
● Conversion between metric and English systems; Millimeters and inches can be switched units;
Can store sound speeds for 5 different materials.
Applicable materials
Suitable for measuring the thickness of good conductors of metals (such as steel, cast iron, aluminum, copper, etc.), plastics, ceramics, glass, glass, fiberglass, and other ultrasonic waves.
Basic Principles
The principle of ultrasonic thickness measurement is similar to that of optical wave measurement. The ultrasonic pulse emitted by the probe reaches the backtesting object and propagates within it. When it reaches the material interface, it is reflected back to the probe. The thickness of the tested material is determined by accurately measuring the time of ultrasonic propagation in the material.
