Assessment of structural integrity and localization of defects and voids in concrete and rock through ultrasonic testing
Structural defects cause serious damages and collapses. Ultrasonic testing provides information on the strength and uniformity of concrete, rock, composites, ceramics, wood, epoxy, refractory materials and can be used to detect and localize voids, pipes, cracks and defects. The ultrasonic pulse echo (UPE) technology extends ultrasonic pulse velocity (UPV) applications to objects where access is restricted to a single side. Proceq Pundit offers the most versatile range of ultrasonic testing instruments.
Pundit Live Array Pro
The wireless Pundit Live Array Pro tomography scanner is connected with an iOS app to an Apple® iPad. It comes with Artificial Intelligence (A.I.) user support and 3D imaging capabilities.
- Real-time tomography
- Smart A.I. user support and positioning
- Increased productivity
Pundit Lab(+)
The Pundit Lab is a flexible UPV test instrument designed primarily for operation in laboratories. It supports all traditional UPV test modes. The Pundit Lab+ comes with an extended feature set.
- Automated combination of the transmitter voltage and the receiver gain for accurate and stable measurements
- Open interface, can be integrated into LabView
- Pundit Lab+ removes the need for external amplification when used with exponential transducers
Pundit 200
The Pundit 200 is a best-in-class UPV test instrument with an extended range of measurement modes. Rugged touchscreen with intuitive user interface for best possible measuring and analysis of the measured data.
- Various measurement modes including Line Scan, Area Scan, Data Logging, compressive strength correlations and E-modulus measurement
- Automatic surface velocity calculation according to standards
- Same instrument can be used with pulse echo transducers
Pundit 200 Pulse Echo
The Pundit 200 Pulse Echo extends the ultrasonic application to objects where access is restricted to a single side. Major applications are slab thickness measurments and the location of voids and delaminations. Rugged touchscreen with intuitive user interface.
New: Pundit® Dry-Point Shear Wave Transducer
- B-Scan is constructed directly on the instrument as the scan is carried out
- Can be upgraded to Multi Channel
- Same instrument can be used with classic pulse velocity transducers
Pundit 250 Array
The Pundit 250 Array is a modular phased array pulse echo instrument incorporating dry-point contact transducers. It features unique real time B-Scans as well as on-site C-scans, P-scans and Volume scans.
- Full modular system allows to increase the number of channels by simply attaching additional probes
- Unique real-time B-scan and panorama B-scan
- Same instrument can be used with classic pulse velocity transducers
