The Dakota ZX-1 will hold a single velocity, making it the perfect choice applications where only one material is being tested day after day. With the preset velocity in the gauge, you simply turn it on and go to work.

The ZX-1 allows the operator to adjust the acoustic velocity (speed of sound through a given material) from 0.0120 to .7300 in/μs. 305 to 18,542 meters/sec to calibrate the gauge for use on a wide variety of materials. The programmed velocity can be locked to prevent accidental adjustment. Typically used on applications where a single material type is tested.

It is designed for measuring wall thickness and the extent of corrosion on a wide range of materials. It is commonly used for checking the thickness of pipes, tanks, plates and other objects. It is designed and built to withstand harsh industrial conditions and is backed by a 5 year limited warranty.
