The faster, easier way to work with standards. It is possible to use our digital test hammer to obtain the avarage value of rebound number. Accessories Testing heads probes The standard 50 kHz transmitter and receiver heads are 12054-4 with the tester.

You may experience issues viewing this site in Internet Explorer 9, 10 or Different heads are available with different nominal working frequency, 24 and kHz which is the usual range for normal concrete: For determining the natural frequency of the ultrasonic pulse transmitted through the material.

Taking, examining and testing in compression BS EN Model Nominal frequency kHz approx. Two pieces are required.

To identify and evaluate Crack depth, Honey combing, Injection quality. Overview Product Details This European Standard, a part of the BS EN series, specifies a method for the determination of the velocity of propagation of pulses of ultrasonic longitudinal waves in hardened concrete, which is used for a number of applications.

After traversing a known path length in the concrete, the pulse of vibrations is converted into an electrical signal by a second tranducer and electronic timing circuits enable the transit time of the pulse to be measured.

Nominal frequency kHz approx. Annexes to this standard provide information on the determination of pulse velocity, factors influencing pulse velocity measurements, and the correlation of pulse velocity and strength.

Main applications Standard UPV measurement with incorporated oscilloscope.

The pulse velocity can be combined with the rebound hammer value for the strength evaluation of concrete. The unit includes an excel spreadsheet for the acquisition of the waveform on the PC for further elaborations. Very often the transit time only is not enough to identify disomogeneities and little damages as for example 125004-4 of concrete which are, on the contrary, well located with this technique by properly processing the acquired waveforms. Customers who bought this product also bought BS EN This European Standard, a part of the BS EN series, specifies a method for the determination of the velocity of propagation of pulses of 1254-4 longitudinal waves in hardened concrete, which is used for a number of applications.
