1.2 Main Functions
Capable of performing measurements on a wide range of material, including metals, plastic,
ceramics, composites, epoxies, glass and other ultrasonic wave well-conductive materials.
Transducer models are available for special application, including for coarse grain material and
high temperature applications.
Probe-Zero function, Sound-Velocity-Calibration function
Two-Point Calibration function.
Two work modes: Single point mode and Scan mode.
Coupling status indicator showing the coupling status.
Battery information indicates the rest capacity of the battery.
Auto sleep and auto power off function to conserve battery life.
Optional software to process the memory data on the PC for MT160.
Optional thermal mini-printer to print the measured data via RS232 port for MT160.
1.3 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:
Where: H-Thickness of the test piece.
v-Sound Velocity in the material.
t-The measured round-trip transit time.
