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(cè)量具有開(kāi)口的中空體內(nèi)部的質(zhì)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(gè)涂層測(cè)量裝置到具有柔性部分增量臂的一個(gè)端部，通過(guò)所述開(kāi)口將所述探針?lè)湃肟招捏w的內(nèi)部，測(cè)量該涂層的所需的數(shù)據(jù)。

 

　　裝置包括一個(gè)靈活的擴(kuò)展器臂為涂層測(cè)量設(shè)備使用。柔性延長(zhǎng)器臂包括一個(gè)細(xì)長(zhǎng)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(duì)的端部；涂層測(cè)量探頭支架部分連接到所述大體剛性的主體部分相對(duì)柔性部分的端部；大幅拉動(dòng)其一端連接到剛體部分和在另一端連接涂層測(cè)量探頭支架部分。
