The Ultrasonic Time of Flight Meter, known also as the Ultrasonic Pulse Velocity Tester, is used for Quality Control and inspection of concrete. It measures the transit time of ultrasonic pulses through concrete for inspection of new and old structures, slabs, columns, walls, fire damaged areas, precast and prestressed beams, cylinders and other concrete forms. Combined with an oscilloscope can identify honey combs, voids, cracks and other non-homogeneous conditions in concrete. Features For the non-destructive evaluation of concrete homogeneity, determination of Dynamic Elastic Modulus, Dynamic Poisson coefficient, concrete resistivity (combined with other determinations). Compliant to EN 12504-4, ASTM C597-09. Ergonomic, compact and portable. Battery operated. Large LCD monochromatic display (128 x 64 pixel). Internal memory for storing up to 250 measurements.
