“Ultrasonic Pulse Velocity (USPV) Tester battery operated – Conforming to EN 12504-4 and ASTM C597, Model No. E4800 “” Controls””. UPV tester is used for quality control and inspection of concrete. It measures the transit time of ultrasonic pulses through concrete and can be applied to new and old structures, slabs, columns, walls, fire damaged areas, precast and prestressed beams, cylinders and other concrete forms. Combined with an oscilloscope it is suitable to identify honey combs, voids, cracks and other non homogenous conditions in concrete. Low and high frequency transducers are available.
