The PR 8² - Sonic Tester

The PR 8² includes these features:

  • The PR 8² is the first affordable Sonic Tester, utilizing state-of-the-art digital technology to produce fast and accurate readings.It requires no special training to operate.
  • Unlike calipers, the PR 8² will measure where there is access to only oneside. This makes it valuable when measuring roll cage thickness, cylinder walls (before and after boring) and heads
    during porting.
  • The PR 8² measures in two modes. The first mode takes a measurement at the point you place the probe. The second is the Scan mode, which is helpful when measuring cylinder walls and roll cages. Place the probe at the bottom of the cylinder and drag it to the top, the gauge will display the thinnest reading measured.
  • The PR 8² is a lightweight, rugged tool that is resistant to water and oil. Other features include a backlit LCD and a bar graph to indicate signal stability. The 5 year warranty indicates how we
    feel about the quality of the PR 8² .
    The PR 8² can go where you go, to do the work you do, saving you time and money, making fast, accurate measurements.
