Is it possible to measure ultrasonic pulse velocity using the Pundit PD8000?

Ultrasonic pulse velocity measurements are traditionally made with P-waves (compression waves). The Pundit PD8000 provides the alternative of measuring pulse velocity variations using shear waves. A unique feature of the...

Is it possible to detect water filled voids with ultrasonic pulse echo?

Yes, it is possible to detect water-filled voids. One of the reasons that shear waves are used in the Pundit PD8000 instruments is that in comparison with P-waves (compression waves), they are better suited to detecting...

How deep can I measure with the Pundit PD8000?

There is no definitive answer to this question as it depends very much on the concrete quality and the amount of steel present. Using the Pundit PD8000 instrument with the Far Field macro selected (low frequency and high...
