It is possible to use our digital test hammer to obtain the avarage value of rebound number.

You may experience issues viewing this site in Internet Explorer 9, 10 or This determination is suitable for 1250-44 examination of the pulse path and gives indications about possible cavities, delaminations, multi-layer elements or othjer similar dishomogeneities. Determination of ultrasonic pulse velocity Status: Two pieces are required. The unit includes an excel spreadsheet for the acquisition of the waveform on the PC for further elaborations.

Ultrasonic pulse analyzer

Supplied with hard plastic carrying case. Very often the transit time only is not enough to identify disomogeneities and little damages as for example microcracking of concrete which are, on the contrary, well located with this technique by properly processing the acquired waveforms. The meter features a very accurate measurement of the transit time. Learn more about the cookies we use and how to change your settings.
