These punched aluminium combs offer the user a low cost method of measuring the wet film thickness.
The combs, being punched from aluminium, are not as accurate as precision formed stainless steel wet film combs and have a shorter lifespan.
Supplied in a pack of 10 combs, each comb has Metric (25 - 3000μm) on one side and Imperial (1 - 118mils) on the other.
