Stainless Steel Wet Film Comb Hexagonal Gauge 25-3000um These hexagonal precision formed stainless steel wet film combs are long lasting and reusable and are supplied in a range of thicknesses measuring up to 3000 um (120 mils). These six sided combs vary in size, giving any 24 or 36 measurement steps, depending on the comb, providing added accuracy. Using a wet film comb Place a comb perpendicular to and touching the substrate. Hold the comb in position and wait a few seconds until the teeth are wet. Remove the comb from the film. The wet film thickness lies between the biggest value'coated' or'wet' tooth and the smallest value'uncoated' or'dry' tooth. Name: Stainless steel hexagonal wet film comb Measuring range: 25-3000um Scale process: scale Usage 1. Immediately after the various coatings are applied, the wet film thickness gauge is placed vertically on the flat surface of the workpiece coating, and the coating thickness can be measured immediately. 2. After use, the instrument should be wiped clean and placed in a dry place. 3. Calculation methods, such as 2000 Micrometre: maximum scale of wetting 2600 Micrometre: minimum scale not wetted The thickness of the wet film is between 2000 Micrometre and 2600 Micrometre Colour: silver Material: stainless steel Size: 74 x 65 x 375mm Package Contents: 1 x wet film thickness meter Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
