In the present invention, an inspection hole (17) is formed at the longitudinal-direction lateral surface of a boiler water tube (10a), the base side of a guide pipe (16) is connected to the inspection hole (17), and a closing member (24) is continuously attached to the guide pipe (16). When the thickness of the boiler water tube (10a) is measured, the closing member (24) is detached from the guide pipe (16), an ultrasound probe (18) is inserted from the tip side of the guide pipe (16) into the boiler water tube (10a), and the ultrasound probe (18) is caused to move within the boiler water tube (10a). Se forma un orificio de inspección (17) en una superficie de un tubo de agua de calentador (10a) en una dirección longitudinal, un lado de base de un tubo guía (16) se conecta al orificio de inspección (17), y usualmente, un elemento de cierre (24) es acoplado al tubo guía. En un caso donde se mide el grosor del tubo de agua de calentador (10a) es medido, el elemento cierre (24) es liberado del tubo guía (16), una sonda ultrasónica (18) es insertada dentro del tubo de agua de calentador (10a) desde un lado de punta del tubo guía (16), y la sonda ultrasónica (18) es desplazada dentro del tubo de agua de calentador (10a).
