A method and apparatus for measuring the quality, e.g., thickness, porosity, or corrosion rate, of a coating inside a hollow body having an opening. The method comprises attaching a probe from a coating measuring device to one end of an extender arm having a flexible portion therein, placing the probe inside the hollow body through the opening, and making the desired measurements of the coating.

 

　　The apparatus includes a flexible extender arm for use with a coating measuring device. The flexible extender arm comprises an elongated, substantially rigid body portion; a handle assembly connected to one end of the substantially rigid body portion; a flexible portion connected to an opposite end of the substantially rigid body portion; a coating measurement probe holder portion connected to an end of the flexible portion opposite the substantially rigid body portion; and a pull connected at one end thereof to the substantially rigid body portion and connected at an opposite end thereof to the coating measurement probe holder portion.

 

　　

　　一种用于测量具有开口的中空体内部的质量，例如，厚度，孔隙率，或腐蚀速率，涂层的方法和装置。该方法包括附加的探针从一个涂层测量装置到具有柔性部分增量臂的一个端部，通过所述开口将所述探针放入空心体的内部，测量该涂层的所需的数据。

 

　　装置包括一个灵活的扩展器臂为涂层测量设备使用。柔性延长器臂包括一个细长的，基本上刚性的主体部分； 手柄组件连接到所述大体刚性的主体部分的一端； 柔性部分连接到所述大体刚性的主体部分的相对的端部；涂层测量探头支架部分连接到所述大体刚性的主体部分相对柔性部分的端部；大幅拉动其一端连接到刚体部分和在另一端连接涂层测量探头支架部分。
