Ultrasonic pulse velocity (UPV) test instrument to examine the quality of concrete and other materials such as rock, wood and ceramics.
It provides an extended range of measurement modes and superior features for on-site testing: Assess the concrete uniformity using standard A-Scans, Line Scans and the new Area Scan functionality, estimate the compressive strength of concrete or measure the surface velocity and the depth of perpendicular cracks. The Data Logging measurement mode allows the automation of long term measurements.
The intelligent software supports directly accessible settings in real time from the measuring screen. The highest resolution and sharpest image available in the market allows best possible analysis of the measured waveforms.

Comprehensive Measurement Modes
Line Scans
Assesses the concrete uniformity and detects cracks as well as other defects. The measured pulse velocities are
displayed as a line.
Pulse Velocity
Calculates the pulse velocity of the material under test.
Compressive Strength
Determines the compressive strength using Ultrasonic Pulse Velocity correlation, or by using SONREB.
Crack Depth
Determines the depth of perpendicular cracks according to BS 1881.
Surface Velocity
Determines surface velocity according to BS 1881.
Transmission Time
Measures the transmission time.
Distance
Calculates the distance between the transducers.
Additional Measurement Modes
E-Modulus
Determine the dynamic E-Modulus of a material (e.g. concrete or rock) by measuring P- and S-wave pulse velocties.
- Direct calculation of the E-Modulus on the instrument
- Measure P- and S-wave velocities on the same screen (Dual Cursor)
- Poisson’s Ratio also calculated on PL-Link software
Data Logging
Set up automated test sequences for long term measuring applications.
- Countdown timer indicates time to next measurement
- Pulse velocity development shown graphically on screen
Area Scan
2D-visualization for uniformity testing on structural elements.
- User definable colour classification based on pulse velocity or transmission time
- User definable grid pattern for small to large scale measurements
- All measurements can be edited (deleted, re-measured)
