BYK-Gardner Comb Gage

BYK-Gardner Comb Gage is a wet film thickness measuring tool used to evaluate the thickness of coatings, paints, varnishes, inks, and other applied film materials while they are still wet. This measurement is important to help operators ensure that the coating is applied at the correct thickness before drying or curing, so the final result can meet the required quality specification.

During the coating application process, wet film thickness control helps prevent layers from being too thin, too thick, uneven, or outside the target dry film thickness. Comb gage works based on a notch gage principle, using multiple measurement points with different clearances to estimate the wet film thickness. This method is practical, fast, and highly useful for direct inspection in production areas or field applications.

BYK-Gardner Comb Gage is available in various materials such as stainless steel, aluminum, and plastic, as well as different shapes including square, rectangle, and hexagon. Single scale or dual scale options in microns and mils are also available to match different measurement requirements. This product is suitable for architectural coatings, industrial coatings, automotive coatings, protective coatings, printing inks, wood coatings, packaging, and other applications requiring fast and cost-effective wet film thickness control.
