The AV 2000
An innovative approach to air void analysis

Braun Intertec Corporation patented technology

The patented AV 2000 Air Void Analysis System is an advanced, complete hardware and software package for performing computerized air void analyses of hardened concrete samples.

How does it work?

Computer-controlled microstepping motors move the concrete sample beneath a stereoscope. The operator views the test area through the stereoscope and presses buttons to indicate the presence of air voids and aggregates. The user-friendly program calculates air void parameters and generates a client-ready report, which can be viewed on screen, printed or saved on disk for further analysis.

Easy operation

Samples are scanned from left to right, or top to bottom. Traverse lines are automatically distributed evenly over the test area selected by the operator. Data collection is performed through the ergonomically designed button pad. The button pad commands are customized by the operator using the system's intuitive, easy-to-use software. This software also offers on-line help for each program option and function.

"Using the AV 2000 approach proved to be instrumental in providing a significant time savings to our linear traverse testing and analysis. It made my job easier "  Dave Linell, Lab Supervisor, Minnesota Department of Transportation
