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.

 

　　

　　一種用于測量具有開口的中空體內部的質量，例如，厚度，孔隙率，或腐蝕速率，涂層的方法和裝置。該方法包括附加的探針從一個涂層測量裝置到具有柔性部分增量臂的一個端部，通過所述開口將所述探針放入空心體的內部，測量該涂層的所需的數據。

 

　　裝置包括一個靈活的擴展器臂為涂層測量設備使用。柔性延長器臂包括一個細長的，基本上剛性的主體部分； 手柄組件連接到所述大體剛性的主體部分的一端； 柔性部分連接到所述大體剛性的主體部分的相對的端部；涂層測量探頭支架部分連接到所述大體剛性的主體部分相對柔性部分的端部；大幅拉動其一端連接到剛體部分和在另一端連接涂層測量探頭支架部分。
