Overview:

Pfund Thickness Gauge

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 it leaves a trace. The diameter of this mark varies depending on the thickness of the coating, which can easily be assessed from the conversion table supplied with the instrument.

Wet Film Thickness

It is important that a coating is applied to the correct thickness. Applying too much wet coating will not only waste and money, but also there is also a possibility of the coating cracking during the curing process. Too little coating and there is a chance that the substrate will not be sufficiently covered.

To control process variables, it is often desirable to measure whilst the film is still wet. Wet film measurements are also useful for systems where the dry film thickness can only be measured destructively.

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 it leaves a trace.

• Ideal for measuring the thickness of translucent products (varnish, oils etc.)

• Measurement range of 2.25 - 360µm (0.09 - 14.17mils)

Standards:

ASTM D 1212-D, NF T30-125
