Elcometer Home Page

Precision formed in stainless steel to be long-lasting and reusable, these hexagonal wet film combs are supplied in a range of thicknesses and can measure up to a maximum thickness of 3000µm (120 mils). This high upper value allows measurement of thick coatings which are difficult to test by other methods.

How to use a wet film comb

  • 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 value.
