PURPOSE:To realize an ultrasonic inspection device which not need resetting of a delay time for enlarged display even if a water temperature is changed. CONSTITUTION:An ultrasonic inspection device having an elevating function on and under the water surface is provided with a tank 3 having an inflow port 3a, a temperature sensor 7 for measuring a water temperature provided in the neighborhood of the inflow port 3a, a corresponding table 9a for water temperature and sound speed and a calculating means for modifying a delay time t0 set according to the ratio between a first speed t0 acquired corresponding to the water temperature from the table 9a when setting the delay time and a second speed of the current water temperature so as to acquire it as a second time t1, and a wave form of an ultrasonic echo is enlarged and displayed according to the timing delayed by the second time t1. |
