Dakota Ultrasonics ZX-2

Dakota Ultrasonics ZX-2 Ultrasonic Thickness Gauge is a basic fixed velocity gauge that requires no special training to operate. Calibration is done by simply scrolling to a known material velocity or selecting a common material from a list of material types in the ZX-2.

These gauges were designed and built to withstand the roughest industry conditions, are affordable, and are backed by a 5-year limited warranty.

If you’re looking for a quality instrument to reliably meet or exceed your application expectations, look no further.
