The PVX finishes the line of PX gauges with class. This thing is loaded with all of the features of the PX gauges and a lot more. Four selectable display options (RF, Rectified, B-Scan, and Large Digits). An Internal data logger that stores a total of 12,000 readings and waveforems, 64 user custom definable setups, selectable transducer table for improved linearity, multiple modes with the single press of a button, multiple calibration and material selection options, and auto waveform find - just to mention a few! This is all nicely packaged in a very mini portable aluminum extrusion for extra durability, not to metion, portability! The PVXview java based PC software makes this thing a complete kit, and then some!
