- 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 velocities.
- 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)
