The model MT660 is a multi-mode ultrasonic thickness gauge. Based on the same operating principles as SONAR, the instrument is capable of measuring the thickness of various materials with accuracy as high as 0.1/0.01 /0.001millimeters.
The multi-mode feature of the gauge allows the user to toggle between pulse-echo mode (flaw and pit detection), and echo-echo mode (eliminate paint or coating thickness).
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: H=v×t/2
Where:
H-Thickness of the test piece.
v-Sound Velocity in the material.
t-The measured round-trip transit time.
Operating Temperature: -20℃~+60℃;
Storage Temperature:-30℃~+70℃
Relative Humidity ≤90%;
The surrounding environment should avoid of vibratin, strong magentic field, corrosive medium and heavy dust.
