    CHAPTER ONE INTRODUCTION The Dakota NDT model FX80 is both, an ultrasonic flaw detector, as well as an ultrasonic A/B Scan thickness scope, in a single unit. It’s a combination of both our CMX Series, as well as our new FX80 flaw detector series. Why is this advantageous? Thickness gauge are specifically setup to very accurately measure thickness, locate pits, flaws and blind surface corrosion.

This method uses a combined empirical and mathematical model to eliminate the need for a large range of reference standards, generally required when using the DAC or TCG methods.
