Dakota Ultrasonics ZX-1 Ultrasonic Thickness Gauge

Dakota Ultrasonics ZX-1 is a basic fixed velocity gauge that requires no special training to operate. Calibration is done by simply scrolling to a known material velocity. The gauge was designed and built to withstand the roughest industry conditions, are affordable, and 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.
