Dakota Ultrasonics CMX

Dakota Ultrasonics CMX

Dakota Ultrasonics CMX v2.0 has all features of the ZX gauges with a ton of advanced features. Measure material and coating thickness simultaneously, while still detecting pits in a single mode (PECT). Auto-probe zero, auto probe recognition, auto temperature compensation are also included. Selectable Large Digits and B-Scan display options, up to 64 custom user-definable setups, a selectable transducer table for precision linearity, and material and coating calibration options are also available.

Dakota Ultrasonics CMX standard thru paint mode is still included and ongoing.

Switch between modes, according to the transducer, recognized or manually selected. 5 position 12dB gain switch allows the user to adjust to certain material types and be successful with common but difficult application scenarios. A built-in TDG (time-dependent gain) feature is incorporated into our transducer list for use with attenuative materials. This gauge is really loaded with a ton of features and added benefits. It’s all very nicely packaged in small portable aluminum extrusion for extra durability. USB-C connectivity, 4GB internal SD memory with a file system. Screen capture to .tif. Our DakView java-based PC or MAC OSX software is also part of the kit.
