Pundit Array

Read full description

Pundit Array: Consolidated power in a single device for structural imaging, object and defect detection with ultrasound pulse echo. Also including wide area grid scanning for thickness and pulse velocity variation mapping. The idea behind Pundit is timeless: to make deep concrete imaging effortlessly precise and clear. Rugged, modular arrays of ultrasonic transducers deliver reliable defect localization and thickness measurement of concrete structures. Pundit Array app and the new Pundit PD8050 transducer array build on that theme: together they are the world's lightest, wireless, AI - assisted and cloud-enabled inspection solution of its kind. This solution allows you to scan deep into concrete faster than has ever been possible before. Uniquely create large scale 2D and 3D images and view with augmented reality directly on site. Improve your inspections with unmatched image precision, sharpness, focus and stability thanks to sophisticated algorithms. Scan over wide areas with the grid scan mode and create heat maps to localize variations in thickness. Combine this with the unique pulse velocity tag to localize variations in concrete quality. Or go further and use this in combination with the methods described in the European standards EN12504-4 and EN13791 to estimate concrete compressive strength. Enjoy the new features included in this app release to increase on-site productivity with a clean, intuitive user interface. Make measurements a breeze with real-time image adjustment, auto-gain, assisted calibration and automated positioning. Annotate measurements with photos, voice memos and comments in the Logbook. Access and share with colleagues anywhere anytime, thanks to the Screening Eagle Technologies Workspace environment. Export raw data of your measurements for post-processing in third party applications. Ultrasonic Pulse Echo detects structural features and flaws other technologies cannot see, and that is why it is the perfect complement to structural inspection with Proceq GPR Live and Profometer PM8000. Download the free app now and explore the state of the art ultrasonic pulse echo with the included demo files.
