Made of stainless steel and with an aluminum grip.
Using a wet film wheel
Roll the wheel by wet coating until the central wheel touch the film. The corresponding point on the scale indicates the thickness. When you know the volume to solids ratio of the coating, which usually contained inthe product data sheet, you can use the wet film thickness to predict the dry film thickness.
Packing list: Wet film thickness wheel and protective case.
