Wet Film Comb Thickness Gauge 25-3000μm Hexagonal Rust Free
Description:
Teeth or notches are machined into the sides of the gauge. The teeth or notches on each side of the gauge are referenced to each other. For a given side, the two outside teeth or notches are the same size and are actually a zero reference datum which represents the substrate. All the other teeth or notches on the same side are of shorter lengths than the outside teeth or notches and represent different distances from the outside edge zero datum teeth. These different distances represent the surface of the wet coating thickness to be measured. The teeth or notches are graduated in MILS (0.001″). In the diagram, 90 is the biggest value wet tooth and 100 is the smallest value dry tooth. Therefore, the wet film thickness is between 90 and 100 mil/thou,If the volume to solids ratio of the coating is known (if not contact the coating manufacturer) then the wet film thickness can be used to predict the dry film measurement, To use combs on pipes, measure along the longitudinal axis (lengthways) of the pipe.

How to use Wet Film comb:
Hold the comb perpendicular to the wet film and press the edge of the comb into the film until it is stable on the substrate.
2. Remove the comb from the wet film.
3. Examine the teeth of the comb and locate the last tooth which is wetted. Read the thickness value of this tooth. The wet film thickness is between this value and the thickness value of the next dry tooth.
