Standard Range: 0.040 to 6.00 in / 1.00 to 150.00 mm
Range in Cast Steel & AL: 0.040 to 1.50 in / 1.00 to 38.00 mm

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 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 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.

Transducer and Probe Information

For Engine Blocks (Cylinders & Decks)
One probe is usually good for use on both Cast Aluminum and Cast Iron Engine Blocks. The 2 inch radius allows the probe to measure the concave surface inside cylinders. The radius is gentle enough that the same probe can also be used to measure on the flat surfaces "decks" on the block. This one probe will work for over 90% of Cast Aluminum or Cast Iron Blocks.

T-104-2120
> 0.500"/5MHz with 2 inch radius
> this is the standard probe supplied with PR-82

*In instances where the above probe does not work, or if the block is made from a very old Aluminum Cast Aluminum, an alternate probe should be specified p/n T-104-4120 (0.500"-10MHz), also supplied with a 2" radius.

For Heads (Ports)
Probe selection depends upon type of material; cast iron or cast aluminum. This probe has a 0.55" radius and is supplied with either a 1 inch wand or 9 inch wand, depending upon user preference.

Cast Iron
> 0.250"/5MHz with 0.55" Radius
with 1 inch wand T-162-2110
with 9 inch wand T-132-2110

Cast Aluminum
> 0.250/10MHz with 0.55" Radius
with 1 inch wand T-162-4110
with 9 inch wand T-132-4110

For Chassis Tubing
This would be used by chassis builders as well as sanctioning bodies (i.e. NHRA, ARCA, etc.). One probe is normally suitable for any application, assuming they do not want "thru-paint" capability.

T-101-4000
> 3/16"-10MHz flat bottom (no radius)
