Ultrasonic Pulse Velocity Test

Home / Ultrasonic Pulse Velocity Test

The Ultrasonic Pulse Velocity Analyzer model MATEST C372M was used for measuring the velocity of ultrasonic pulses through concrete section  providing  information on crack nature i.e., depth orientation and the level of penetration within a structural element on which the crack is appearing on site or in the laboratory. It can also be used for estimating times for formwork striking.

A coupling material is usually applied on the locations where the transducers are to be placed. Care is taken not to move the transducers while reading is being taken, as this can generate noise signals and errors in measurements. The transducers are held onto the surface of the material until a consistent reading appears on the display. This is the time in microsecond for the ultrasonic pulse to travel the test distance.
