DAKOTA high-precision ultrasonic thickness gauge from the United States

High precision ultrasonic thickness gauge PZX-7DL

The new generation of precision ultrasonic thickness gauges PZX-7 and PZX-7DL launched by DAKOTA in the United States are upgraded products of PX-7/PX-7DL, with high precision, high resolution and other characteristics. Equipped with multiple measurement modes, multiple diameter, high-frequency or low-frequency probes can be selected to solve many potential applications. In the echo echo mode, the thickness of the material can be measured without removing the paint or coating.

Compliant with NIST and MILSTD-45662A standards.
