Claims
- 1. A method for measuring thickness of a coating inside a hollow body having an opening, said method comprising the steps of:
- (a) attaching a coating thickness measurement probe to one end of an extender arm, wherein a central axis of said probe and a central axis of said extender arm form an angle, said extender arm comprising:
- (i) an elongated, substantially rigid body portion;
- (ii) a flexible portion connected to one end of said substantially rigid body portion;
- (iii) a coating measurement probe holder portion connected to an end of said flexible portion opposite said substantially rigid body portion; and
- (iv) a pull connected at one end thereof to said substantially rigid body portion and connected at an opposite end thereof to said coating measurement probe holder portion for adjusting said angle;
- (b) extending said probe inside the hollow body through the opening;
- (c) adjusting said angle;
- (d) contacting the probe with the coating inside the hollow body; and
- (e) measuring the thickness of the coating.
- 2. The method according to claim 1, wherein said angle ranges from 0 to about 135.degree..
- 3. The method according to claim 1, wherein the adjusting step comprises loosening a locking mechanism on the extender arm, and pushing or pulling a portion of the extender arm to flex the flexible portion thereof.
- 4. The method according to claim 1, wherein the hollow body is a gas storage vessel.
