Apparatus for measuring coating quality

Abstract

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.
