Ultrasonic pulse velocity tester
An apparatus for detecting anchor bolt pullout strength. The apparatus includes circuitry configured to process ultrasonic measurement signals using at least one of a direct, an indirect, and a semi-direct measurement technique. Further, the apparatus comprises a first probe and a second probe connected to the circuitry, and memory for storing data detected by the first and the second probe. The memory is connected to the circuitry and a data connection connected to the circuitry and configured to communicate with an external network. An ultrasonic signal is transmitted by the circuitry through the first probe and rebounded by the second prob. The circuitry detects a time duration to receive the rebounded signal, storing the time duration to the memory, and comparing the time duration to reference measurement data. The reference measurement data may be stored in at least one of the memory and the external network.
