MVX Series A/B Scan Ultrasonic Thickness Gauges

The MVX includes these features:

  • The physical size, weight, and display resolu-tion are just a few of the benefits of the MVX.
  • The adjustable square wave pulser provides the flexibility necessary for both high resolution and
    penetration requirements.
  • The MVX is equipped with multiple viewing options to provide users with a complete set of
    inspection tools: (RF waveform, +/- Rectified waveform, Time based B-Scan, and Large Digits).
  • The A-Scan rectified mode is commonly used for detecting flaws/pits in pulse-echo mode
    and measuring thru-paint and coatings inecho-echo mode.
  • The time-based B-Scan feature of the MVX displays a cross section of the test material.
    It is commonly used to display the profile of the bottom surface of the test material.
  • Built-in hardware AGC gain control for thru-paint measurements in multi-mode operation.
  • The variety of calibration options is just one more example of MVX's overall versatility.
  • The MVX has the ability to store 64 custom user-defined setups. All factory setups can
    be selected, edited and saved to any setup location.
  • MVX is equipped with an alpha-numeric data logger to provide increased versatility for those
    custom reporting needs.
  • The built-in transducer types offer increased linearity between transducers.
  • The high speed scan feature speeds up the inspection process by making 32 measure-ments
    per second. Remove transducer from the test material and display the minimum
    measurement scanned.
  • Use the visual alarm to set hi and lo limits for applications requiring specific tolerances.
    If the actual thickness value is above or below the limits, a red light is illuminated.
  • Use the find feature to locate the detection
    point, while automatically adjusting the display to bring the signal into view.
  • MVX also comes complete with our Windows® PC software for transferring data to and
    from a PC.
  • 2 year limited warranty
