Abstract: PURPOSE:To precisely measure the depth and size of a surface defect, by subsidiarily using an echo of the end part of which pulse repetition frequency is reduced from the opposite side by two-probe method. CONSTITUTION:A ultrasonic pulse of which pulse repetition frequency is reduced, is transmitted from a transmitting/receiving probe 4 and an exclusive transmitting probe 4' through a transmission part 3 controlled by a synchronous part 1 and a transmission part 3' controlled by the synchronous part 1 and a frequency- dividing circuit 2 respectively and the echo from the upper end part of the surface defect 8 is received by the probe 4.

Consequently the beam way lengths W1, W2 from the probes 4, 4' are made approximately equal to the time axial way W of the cathode-ray tube 7, so that the position (d) of the upper end part is determined. The position of the lower end part is determined in the same manner and the end part echo is precisely discriminated by the two-probe method, so that the depth and size of the surface fault can be precisely measured.
