Ultrasonic Pulse Velocity Tester is a portable non-destructive testing instrument used to evaluate the quality and integrity of concrete by measuring the velocity of ultrasonic pulses through the material. It helps detect cracks, voids, honeycombing, and other internal defects while assessing concrete uniformity and durability. Compliant with ASTM C597, EN 12504-4, and IS 13311 (Part 1), the UPV Tester is ideal for construction sites, laboratories, bridges, dams, tunnels, and infrastructure inspection.
