Wet Film Thickness Gauge

• 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
