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.

• Ideal for measuring the thickness of wet translucent products such as varnishes, oils, etc.
• Measurement range of 2.25 – 360μm (0.09 – 14.17mils)
