PR 8V 001

DAKOTA ULTRASONICS PR-8V Sonic Tester Racing

Only by Request

The PR-8V is our most advanced sonic tester designed for the racing industry. It’s most commonly used to measure the thickness of cylinder walls, head ports, decks, chassis tubing, body panels, and windshields. The time-based B-Scan feature of the PR-8V displays a cross section view to see the profile/contour of the back surface while scanning cylinders.

Standard (Pulse-Echo mode) for use with a variety of common material types and variable gain options (vlow, low, medium, high, vhigh) in 3dB increments (40 to 52dB range), for increased penetration or resolution. Use the Multi-Mode (Echo-Echo mode) feature to measure chassis tubing with or without paint and coatings. Built-in automatic gain control and selectable gain options (low, medium, and high).

A variety of calibration options, common material list, the ability to store 64 custom setups, high speed scanning, and alarm options are a few of the features in the PR-8V. The PR-8V is equipped with a 4GB internal SD memory card, selectable GRID or ENGINE data structures, and used in conjunction with our PC & OSX software for your reporting needs.

ELECTRONIC PLATFORM (What’s inside the box):

 

  • Built-in transducer types offer increased linearity between transducers.
  • The high speed scan feature provides better representation during the scanning process, by increasing the sample rate.
  • Use the visual and audible alarm to set Hi and Lo limits to signal the inspector when the measurements are out of tolerance.
  • The PR-8V also comes complete with our Windows PC & OSX software for viewing and reporting B-Scans, Cylinder Maps, general measurements, and settings.
  • 2 year limited warranty.
