Higher Sensitivity Coating Thickness Meter , Long Standby Coating Thickness Gauge MT200

Mitech MT200 Ultrasonic Thickness Gauge with accuracy as high as 0.1/0.01 /mm higher sensitivity 

Overview

The model MT200 is a digital ultrasonic thickness gauge. Based on the same operating principles as SONAR, the MT200 is capable of measuring the thickness of various materials with accuracy as high as 0.01 millimeters, or 0.001inches. It is suitable for a variety of metallic and non-metallic materials.

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.
