PURPOSE: A probe unit for an ultrasonic flaw detecting test is provided to minimize the generation of bubbles caused by jetting pressure in a medium liquid discharging process by discharging medium liquid by weight while storing the liquid inside a storage chamber. CONSTITUTION: A probe unit for an ultrasonic flaw detecting test comprises a housing unit(100), a sensor fixing block(200), and an ultrasonic sensor(400). The housing unit includes a storage chamber for storing medium liquid in an internal space. A liquid supply port for supplying the medium liquid to the storage chamber is formed in one side of the housing unit. The sensor block, which underside is exposed to outside, is mounted in the internal space of the housing unit. Liquid discharging holes are communicated with the storage chamber so that the medium liquid stored in the storage chamber is downwardly discharged. |
