  • 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.


  • Line scans for concrete uniformity assessment
  • Zoom and scroll for precise A-Scan inspection
  • Area Scan Mode extends the possibilities for uniformity testing of larger structures
  • Data logging allows the automation of long-term measurements
  • E-Modulus measuring mode to determine the Poisson’s Ratio of materials
  • On board storage and review of waveforms
  • Settings directly accessible on measuring screen
  • Dual cursor for manual A-Scan evaluation
  • Separate cursor to measure signal amplitude

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.


  • Calculates the distance between the transducers.

Additional Measurement Modes


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)
