Remove the gauge from the wet film to measure the thickness. The wet film thickness corresponds to the gap between the shortest tooth that contacts the film and the adjacent tooth that does not. Repeat the measurement in two different locations to obtain representative results. After use, clean and dry the wet film thickness gauge thoroughly. Package Included: 1 x Wet Film Comb 1 x Black Case
