Leeb 333 Ultrasonic Thickness Gauge | High-Precision

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

Application Scope:

This instrument can measure various plates and processed parts. Another important application is monitoring pipelines and pressure vessels in production equipment to assess the degree of thinning caused by corrosion during use. It is widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace, and other fields.

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 material and reflects back when it reaches the material boundary. By measuring the time taken for the ultrasonic waves to travel through the material, the thickness of the tested material is determined.

Features:

1. Measures the sound velocity of composite and unknown materials with a known thickness.
2. Sets upper and lower tolerance limits with an automatic alarm when exceeded.
3. Chinese and English operation menus.
4. Status indication function.
5. Suitable for measuring the thickness of metals (such as steel, cast iron, aluminum, copper, etc.), plastics, ceramics, glass, fiberglass, and other good ultrasonic conductors.
6. Instrument calibration function.
7. Coupling status indication function.
8. High-brightness LED backlight display for use in low-light environments.
9. Battery level indicator to display remaining battery life.
10. Power-saving functions such as automatic sleep and auto shutdown.
11. Compact, portable, and highly reliable, suitable for harsh operating environments with resistance to vibration, impact, and electromagnetic interference.
12. Metric and imperial unit selection.
