The Wet film Wheel consists of three circles. The central circle is of smaller diameter and is eccentric to the two outer circles. By rolling the gauge through a wet coating, the centre disc eventually touches the film. This point on the scale indicates the thickness.

If the volume to solids ratio of the coating is known, then the wet film thickness can be used to predict the dry film thickness.

This wheel has a range from 0 to 50µm with scale divisions of 2.5µm

* Continuous Scale results in ±5% measurement accuracy.
* Suitable for flat and curved surfaces.
* Stainless steel giving a hard-wearing instrument which can be cleaned with solvents for reuse.
