The Elcometer 3233 Pfund Thickness Gauge is used to measure the film thickness of wet translucent products such as varnishes, paints and oils.
Available in aluminium or stainless steel this instrument consists of two concentric cylinders, one sliding inside the other. A spherical glass lens is fitted to the end of the central cylinder and when pressed into the wet film, leaves a circular trace.
The diameter of the mark on the lens is measured and, using the supplied conversion table, the thickness of the coating can be easily assessed.
