Dakota MVX

Compare the MVX to the DMS2tm and the 37DLtm and you will find that you can get all the features you need in an easier to use, more compact and affordable package.

Digital Display: For basic applications just set the display mode to DIGITS

A-Scan: Allows you to see the return signals, which help verify that the correct echo is being measured and avoid false thin measurements, that may be caused by laminated or dirty steel.

B-Scan: Draws a picture of the back surface, instantly recognizes: pitting, erosion and laminations.

Through-Coating: Echo-Echo Mode allows correct measurements on painted and coated materials.

Data-Logging: Stores up to 15,000 measurements, together with A-Scans and B-Scans in multiple files that can be dumped to a PC and exported to an EXCELtm file if desired.

"The MVX finishes the line of MX gauges with class. This thing is loaded with all of the features of the MX gauges and a lot more. Four selectable display options: RF, Rectified, B-Scan and Large Digits. The CMX also has an internal data logger that stores a total of 12,000 readings and waveforms, 64 user custom definable setups, selectable transducer table for improved linearity, thru paint mode with the single press of a button, multiple calibration and material selection options and auto waveform find – just to mention a few! Equipped with a single element flaw prove-up mode for basic angle beam inspections. This is all nicely packaged in a very mini portable aluminum extrusion for extra durability and portability! The MVXview java-based PC software makes this thing a complete kit, and then some!"
