The Dakota NDT ZX1 fixed velocity thickness gauge is a basic dual‑element gauge capable of locating blind surface pitting and internal defects. It is pre‑calibrated for steel, allowing out‑of‑the‑box measurement. Calibration is done by scrolling to a known material velocity. Pulse-Echo measurement range: 0.025–36in (0.63–914.4mm). Resolution 0.001in (0.01mm).

Features include 120MHz FPGA timing, 150‑volt square wave pulser, velocity range 0.0120–0.7300 in/μs (305–18,542 m/s), pulse repetition frequency 200Hz, display update 10Hz. Automatic V‑path/dual path error correction. Adjustable material velocity. Multi‑function 4.5‑digit LCD.

Designed for rough industry conditions, backed by a 5‑year limited warranty. Custom transducers available for special applications. Suitable for corrosion, pitting, tube/pipe, tanks, boilers, and glass.
