Ultrasonic Thickness Gauge Leeb 322 – Doryang

This machine adopts the ultrasonic measurement principle and is suitable for measuring the thickness of various materials that allow ultrasonic waves to propagate at a constant speed within them and reflect from their backside.

Application Scope:

This instrument can measure various plates and processed parts. Another important application is monitoring pipelines and pressure vessels in production equipment, assessing their thinning due to corrosion during use. It is widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace, and other industries.

Basic Principle:

The principle of ultrasonic thickness measurement is similar to that of optical wave measurement. The probe emits an ultrasonic pulse that propagates through the object. When it reaches the material interface, it is reflected back to the probe. The thickness of the material is determined by measuring the travel time of the ultrasonic waves.

Features:

1. Measures sound velocity of composite or unknown materials with known thickness.
2. Allows setting upper and lower tolerance limits with automatic alarm when exceeded.
3. Provides both Chinese and English operation menus.
4. Status indication function.
5. Suitable for measuring the thickness of metals (e.g., steel, cast iron, aluminum, copper, etc.), plastics, ceramics, glass, fiberglass, and other good ultrasonic conductors.
6. Equipped with instrument calibration function.
7. Can store up to 2000 data points.
8. Coupling status indication function.
9. High-brightness LED backlight display for use in low-light environments.
10. Battery level indicator to display remaining battery power.
11. Power-saving features, including auto sleep and auto shutdown.
12. Compact, portable, highly reliable, and suitable for harsh operating environments with resistance to vibration, impact, and electromagnetic interference.
13. Selectable metric and imperial measurement units.
