Ultrasonic Pulse Velocity - Pundit Lab Plus
Ultrasonic Test Equipment - Pundit Lab+

The Pundit Lab is an ultrasonic pulse velocity (UPV) test instrument which is used to examine the quality of concrete. The Pundit Lab+ comes with an extended feature set, making it particularly suitable for on-site measurements. Naturally it contains all of the features of the Pundit Lab. The new functions include, an integrated gain stage making an external amplifier unnecessary when using long cables or exponential transducers, a real time stamp for recording the time of measurement, a data review list that allows previous measurements to be viewed on site, and a correlation to compressive strength either directly from pulse velocity or in combination with a rebound value (SONREB method).


Standard 54kHz Transduser
A new design with improved performance to increase range and stability.

   150kHz Transducers
These transducers have more resolution, but a decreased range. For use on fine grained samples.
     250kHz Transducers
These transducers have more resolution, but a decreased range. For use on fine grained samples.
   54kHz Exponential Transducers
For use on rough surfaces without couplant. When used in combination with Pundit Lab+ no external amplifier is required.

500kHz Transducers
For use with fine grained materials, such as rock and ceramics.

   250kHz Shear Wave Transducers
For use in combination with standard P-wave transducers to measure the dynamic elastic modulus of the material under test.
                Transducer Holder
Particularly useful for compound measurements such as surface velocity or crack depth.
Pundit® Link

The Windows based software Pundit Link, developed by Proceq, unlocks the full capabilities of the ultrasonic test equipment Pundit Lab+, providing the user with:

  • waveform visualization and analysis turns your PC into an oscilloscope
    interactive adjustment of trigger point 
  • on-line data acquisition 
  • full remote control of the instrument instrument including programmable data logging functionality
  • export of data to third party applications
  • (Pundit Lab+ only) creation of conversion curves for compressive strength (exponential, polynomial)
  • (Pundit Lab+ only) creation of SONREB curves for combined (ultrasonic/rebound value) estimates of compressive strength


How to use the PL-Link Software on the Apple operating system.
