CHAPTER ONE
INTRODUCTION
The Dakota Ultrasonics model MMX-7 is a digital ultrasonic thickness gauge with a
time based B-Scan and alpha numeric data logger. Based on the same operating
principles as SONAR, the MMX-7 is capable of measuring the thickness of various
materials with accuracy as high as
±
0.001 inches, or
±
0.01 millimeters. The
principle advantage of ultrasonic measurement over traditional methods is that
ultrasonic measurements can be performed with access to only one side of the
material being measured.

1.1 Disclaimer
Inherent in ultrasonic thickness measurement is the possibility that the instrument will
use the second rather than the first echo from the back surface of the material being
measured. This may result in a thickness reading that is TWICE what it should be.
Responsibility for proper use of the instrument and recognition of this phenomenon
rest solely with the user of the instrument.
