Product Description
Additional Info
Product Literature


The time-based B-Scan feature of the PR-8V displays a cross section of the opposite surface, allowing engine builders the ability to see the contour of the back surface in cylinders while scanning.

Use the Multi-Mode (Echo-Echo mode) feature, to measure chassis tubing with or without paint and coatings. Built-in automatic gain control.

Selectable low, medium and high gain settings offer the inspector the additional punch power for materials that are hard to penetrate.

The variety of calibration options is just one more example of the PR-8V's versatility.

It stores up to 64 custom setups. Factory setups are available for common applications as well.

The internal Data Logger of the PR-8V has been customized for both the engine builder and the chassis inspector. Selectable cylinder mapping or general alpha numeric file storage will satisfy your reporting needs.

Built-in transducer types offer increased linearity between transducers.

The Fast Scan feature provides a better representation during the scanning process, by making 32 measurements per second. Remove the transducer from the test material to display the thinnest measurement found.

Use the visual and audible alarm, to set High and Low limits to signal the inspector when the measurements are out of tolerance.

The PR-8V also comes complete with our Windows PC software for transferring data to and from a PC and viewing B-Scans, Cylinder Maps and general measurements.
