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 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 thrupaint 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 measurements 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.
