Dakota Ultrasonics MVX

Dakota Ultrasonics MVX

Dakota Ultrasonics MVX v2.0 is our most basic A-Scan thickness scope, with the ability to satisfy the most advanced thickness applications.

It steps outside of our basic digital line of gauges and offers the versatility of a scope-based instrument. Display options are RF, Rectified, B-Scan, and Large Digits.

An alphanumeric data logging format with 4Gb internal SD memory stands to offer far more storage than ever needed. Our custom setup features allow 64 definable setups per file, for as many files as is needed.

Transducer table for improved linearity, thru paint mode with the single press of a button, multiple calibrations, and material selection options, and auto find waveform feature – just to mention a few!

This is all nicely packaged in a very mini portable aluminum extrusion for extra durability and portability!

Our DakView java-based PC or MAC OSX software makes this thing a complete kit, and then some!
