PR-8

PR-8

The PR-82 is

the rst aordable

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 one side.
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
rst 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.
