Variety of Applications
The PR-82 isthe first affordableSonic Tester, utilizingstate-of-the-art digitaltechnology to producefast and accurate readings.It requires no special trainingto operate.
Unlike calipers, the PR-82 will measurewhere there is access to only oneside. This makes it valuable when measuringroll cage thickness, cylinder walls(before and after boring) and headsduring porting.
The PR-82 measures in two modes. Thefirst mode takes a measurement at thepoint you place the probe. The second isthe Scan mode, which is helpfulwhen measuring cylinder walls and rollcages. Place the probe at the bottom ofthe cylinder and drag it to the top, thegauge will display the thinnest readingmeasured.
The PR-82 is a lightweight, rugged toolthat is resistant to water and oil. Otherfeatures include a backlit LCD and abar graph to indicate signal stability.The 5 year warranty indicates how wefeel about the quality of the PR-82.The PR-82 can go where you go, to dothe work you do, saving you time andmoney, making fast, accuratemeasurements.
Simple operator controls virtually eliminate training
Resolution of 0.001 inch (0.01 mm)
Four readings per second for single point measurements or 16 per second in SCAN mode.
Large, back-lit LCD display retains last reading
Switch-selected units for inches or mm
Special-purpose probes are offered for a variety of applications
Includes NIST Calibration Certificate
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.
> 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.
> 0.250"/5MHz with 0.55" Radius
with 1 inch wand T-162-2110
with 9 inch wand T-132-2110
> 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.
> 3/16"-10MHz flat bottom (no radius)
For "thru-paint" capability, when measuring chassis tubing for use with the PR8V
>0.250/5MHz Hi-Damp for use in MMX Mode
