ABSTRACT:
A gauge for measuring the thickness of a wet film on a surface comprises a circular disc having circumferentially spaced, calibrated notches around the outer periphery thereof. Finger grip elements are disposed at opposite sides of the disc and carry the disc for rotation relative thereto. The disc is rolled across the surface relative to the finger grip elements so that the notches are selectively wetted.
