Variety of Applications

The PR-8V thickness gauge is designed specifically for the needs of engine builders and race shops. The time-based B-Scan feature of the PR-8V displays a cross-section of the opposite surface, allowing the 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.

Complete Kit
The PR-8V is supplied as a complete kit with the gauge, probe, 4 oz. bottle of coupling fluid, 2 AA batteries, data transfer cable, Windows Software, NIST Calibration Certificate, and Operating Instruction Manual – all in a foam-fitted carrying case.

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 alphanumeric 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.

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.

  • Selectable low, medium, and high gain settings offer the inspector the additional punch power for materials that are hard to penetrate.
  • Store up to 64 custom setups. Factory setups available for common applications.
  • Selectable transducer types with built-in dual path error correction for improved linearity.
  • Fast-Scan Mode: Takes 32 readings per second and displays the minimum reading found when the transducer is removed.
  • Use the visual and audible alarm to set Hi and Lo limits to signal the inspector when the measurements are out of tolerance.
