Ultrasonic Pulse Velocity (UPV) test includes a simple Non Destruction Test (NDT) testing method, by utilizing ultrasonic waves. In the implementation of UPV testing with direct, semi-direct, and indirect methods give a quick result of different pulse velocity, with the same quality of concrete. Therefore, this study was conducted to get the correlation and correction value of all three testing methods with PUNDIT Lab+ tool on reinforced concrete. The study used a speciment of concrete beams 15x15x60 cm 3 with concrete quality K-275, K-250, K-225 each as much as 3 specimen. The average value of the measurement result with the direct UPV method is 12%, 7% and 5% less than the average value of the semi-direct method of UPV direction vertically, the semi-direct method of the UPV direction horizontally, and the indirect method UPV. Conversion of the measurement results for the direct UPV method of the semi-direct UPV vertical direction, semi-direct UPV direction horizontal and indirect UPV can use the regression equation V d = 0.2462 V sd-v + 3192, V d = 0.1073 V sd-h + 3923.8 and V d = 0.0195 V in + 4341.8.
