The R9 / PR-9 sonic tester is a dedicated design for the racing industry, and commonly used to measure the thickness of cylinder walls, head ports, decks, chassis tubing, body panels, and windshields. An additional benefit is the dual element style of probe with the ability to locate blind surface corrosion or deterioration on the blind surface in the water jacket area prior to boring a cylinder or port. The high speed scan feature takes 100 measurements per second to save time when scanning a complete cylinder. Simply drag the probe from the bottom of the cylinder, at a given clock position in the cylinder, up to the deck area to locate the minimum thickness found. Scan can then be switched off and the user can find the exact location of the minimum thickness.

The PR-9 has three material calibration options (single point, two point, and target velocity) for increased accuracy. Cylinder wall mapping software available for manually creating reports. Finally, our 5 year limited warranty indicates how we feel about the quality.

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-9

*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)
