§  Suitable for measuring metal (such as steel, cast iron, aluminum, copper, etc.), plastics, ceramics, glass, fiber glass and any other good ultrasonic conductors.

§  Dual straight beam probes with different frequencies and crystal sizes are available.

§  Zero calibration, two-point calibration, automatic error correction system.

§  Known thickness, sound speed can be measured, in order to improve the measurement accuracy.

§  Coupling status indicator showing the coupling status.

§  EL backlight for easy use in dimly lit environments.

§  Remaining battery indicator can display the remaining power in real time.

§  Auto sleep and auto power off function to conserve battery life.

§  Small, portable, high reliability for harsh operating environment, anti-vibration, anti-shock and  anti-electromagnetic interference.


Measuring Principle

The digital ultrasonic thickness gauge determines the thickness of a part or structure by accurately measuring

the time required for a short ultrasonic pulse generated by a transducer to travel through the thickness of the  

material, reflect from the back or inside surface, and be returned to the transducer. The measured two-way

transit time is divided by two to account for the down-and-back travel path, and then multiplied by the

velocity of sound in the material. The result is expressed in the well-known relationship.


To make sure the probe working properly, it needs to use couplant to isolate the air between the probe surface

and the measured workpiece surface. The liquid used for the coupling between the probe and workpiece is

called as couplant.
