The MVX v2.0 is our most basic A-Scan thickness scope, with the ability to satisfy 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 alpha numeric data logging format with 4Gb internal SD memory, stands to offer far more storage than ever needed. Our custom setup features allows 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 calibration 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!
