เครื่องวัดค่าความหนา,Landtek,Mul-ti Mode Ultrasonic Thickness Gauge TM-8819-T3,

Features

* Multi-mode: Pulse-Echo mode (used for flaw and pit detection) and Echo-Echo mode (used for measurements eliminating paint or coating thickness).
* Using the latest high performance and low power consumption microprocessor technology.
* Automatic memory material code and sound velocity value, convenient to use.
* Use USB/RS-232 data output to connect with PC.

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 downand-back travel path, and then multiplied by the velocity of sound in the material.
