4、 Working principle:
The TT300 ultrasonic thickness gauge measures thickness by generating ultrasonic pulses through a coupling agent to reach the object being measured, with a portion of the ultrasonic signal reflected by the object's bottom surface. The probe receives the echo reflected by the object's bottom surface, accurately calculates the round-trip time of the ultrasonic waves, calculates the thickness value according to the following formula, and displays the calculation results.

In the formula: H - Measure thickness; V - material sound velocity;
T - The propagation time of ultrasonic waves in the specimen for one round trip.
