Wet film comb gages also know as notch gages are formed on the edge of a piece of material so that each notch has a different clearance from the reference shoulders to its neighbors.

BYK-Gardner offers comb gages in many different materials, such as stainless steel, aluminum or plastic in a variety of shapes: square, rectangle or hexagon. Depending on your application single or dual scale combs in microns / mils are available.

  • Wet film measurement provides first opportunity to do a quick check of the coating and its application process

  • Simple low-cost device which is useful whan approximate values are satisfactory

  • Very useful for coating systems where the dry film thickness can only be measured destructively

  • For measuring, push the comb gage perpendicularly into the film using the measuring range that corresponds to the expected film thickness
  • Remove the comb gage from the coating
  • The wet film thickness will fall between the clearance of the shortest tab that is wet and the clearance of the next shortest dry tab
