Ultrasonic Pulse Velocity - Pundit Lab
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. It features online data acquisition, waveform analysis and full remote control of all transmission parameters. Along with the traditional transit time and pulse velocity measurement, the ultrasonic test equipment Pundit Lab offers path length measurement, perpendicular crack depth measurement and surface velocity measurement. Optimized pulse shaping gives greater transmission range at lower voltage levels. This, coupled with automated combination of the transmitter voltage and the receiver gain, ensures an optimum received signal level, guaranteeing accurate and stable measurements. An integrated waveform display allows manual triggering of the received waveform.

Features
  • Integrated waveform display
  • Remote control: A USB connection and the Pundit Link application allow full remote control of all features of the ultrasonic test equipment Pundit Lab.
  • Open interface: full remote control of the instrument is also possible with third party software
  • Direct data logging on the PC
  • Multiple Power Supply Options: the ultrasonic test equipment Pundit Lab runs on battery supply, mains supply via AC adaptor and can also be powered from a PC via the USB connection.
  • Wide range of transducers: The ultrasonic test equipment Pundit Lab supports a wide range of transducers from 24 kHz up to 500 kHz, making it suitable not only for concrete and rock, but also for other materials such as graphite, ceramics, woods, etc. Exponential transducers for rough surfaces and shear wave transducers for estimation of dynamic modulus of elasticity complete the portfolio.
Accessories
  

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 including programmable data logging functionality
  • export of data to third party applications
Applications

The ultrasonic test equipment Pundit Lab is the most versatile Pundit to date. It has all the functions of the classic Pundit 7 but also offers additional benefits. Designed with laboratory use in mind, its compact size, rugged construction and optimized power consumption make it equally suitable for on-site use.
