Parameter: Measuring Range: 5-118mil Step Graduation : 25um Measuring Procedure : 1. Select appropriate comb according to approximate known thickness. 2. Hold comb perpendicular to surface coating to be measured. 3. Press into coating until the comb stands square on substrate. 4. Wet film thickness is between the highest step which is coated and the next (higher) step which remains uncoated.
