SONIC TESTER

The physical size, weight,

and display resolution are

just a few of the benets

of the PR-8V

▶ 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 oer

the inspector the additional punch power for materials

that are hard to penetrate.

▶

The variety of calibration options is just one more

example of PR-8V’s versatility.

▶

Store up to 64 custom setups. Factory setups

available for common applications.

▶

The internal Data Logger of the PR-8V has been

customized for both the engine builder and the chas-

sis inspector. Selectable cylinder mapping or general

alpha numeric le storage will satisfy your reporting

needs.

▶

Built-in transducer types oer increased linearity

between transducers.

▶

The Fast Scan feature provides a better representa-

tion during the scanning process, by making 32 mea-

surements per second. Remove the transducer from the

test material and display the thinnest measurement found.

▶

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 software for transferring data to- and from a PC, and

viewing B-Scans, Cylinder Maps, and general measurements.

▶ 2 year limited warranty.
