PR-82 Sonic Tester has been modified for the automotive industry. This gauge is commonly used for measuring the thickness of cylinder walls, head ports, decks, tubing, body panals, and windshields. It also has the ability to scan the length of a part to find the the minimum thickness. The PR-82 is back-lit and the unit operates for up to 200 hours on a single set of batteries. It is protected by Dakota Ultrasonics 5 year limited warranty.
The PR-82 utilizes 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 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 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.
