摘要： PURPOSE: A probing device and a proving system for inspecting a tube are provided to inspect tubes of a small diameter, to remarkably reduce time and costs required for an inspection, and to improve the reliability of the inspection. CONSTITUTION: A probing device(300) for inspecting a tube comprises a probe unit(310), an air injection connecting line(320), and a joining unit(330). The probe unit, which is joined to the tube of a small diameter, collects inspection data. The air injection connecting line presses the probe unit by using air so that the probe unit is closely adhered to the tube. The joining unit fixes the probe unit and the tube at an inspection position.
