These reusable precision stainless steel combs are made to be long lasting and are supplied with either Metric or Imperial measurements.
Four separate thickness ranges are available up to a maximum of 1270µm / 50mils and are manufactured to an accuracy of 5% or 2.5µm (0.01mil), whichever is the greater.
Each comb has 10 measurement steps (teeth).
Place a comb perpendicular to and touching the substrate. Hold the comb in position and wait a few seconds until the teeth are wet. Remove the comb from the film. The wet film thickness lies between the biggest value 'coated' or 'wet' tooth and the smallest value 'uncoated' or 'dry' tooth.
