  • 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 through paint and coatings in echo-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 through paint measurements in multi mode operation.
  • 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.
  • CE Certified
  • 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.
  • Includes Flaw Inspection - Prove Up Mode, (special probe required)
  • The high speed scan feature speeds up the inspection process by making 32 measurements per second. Remove transducer from the tesst material, and display the minimum measurement scanned.
  • Includes NIST-Traceable Calibration Certificate

Complete Kit

High Speed Scan Mode B-Scan Mode High Speed Scan Mode
The A-Scan rectified mode is the preferred display view for flaw and pit detection applications and measuring through paint and coatings in the echo-echo mode. The B-Scan view displays a time-based cross section of the test material. It is commonly used to display the profile of the blind or underside of a pipe or tank. The Large Digits view provides a basic digital thickness gauge look and feel. The large display makes it easy for the operator to monitor the thickness readings.
