Thickness Gauges Models 234/333/433 for Coating Plants and Laboratories testing equipment for quality management Technical Description and Operating Instructions

Film thickness measurement plays an essential part in the use and testing of paints and coating materials. The film thickness is a decisive factor in determining appearance, protective qualities and durability. A film which is too thin will afford inadequate protection and reduced hiding power. For this reason, technical specifications stipulate minimum film thicknesses and regular controls must be carried out to ensure that these values are consistent. On the other hand, an excessively thick film is the result of using too much coating material, causing costs to increase accordingly. Furthermore,...

Application Order Information ( 5 pm scale division) (10 pm scale division) (20 pm scale division) (40 pm scale division) On all flat and slightly curved surfaces, as long as the measuring instrument can be applied parallel to the axis of curvature. The equally long teeth 1 and 12 of the comb-shaped measuring instrument (Fig. 2) penetrate the wet film to the substrate. Between these two end positions teeth 2 to 11 are formed at a progressively increasing distance from the substrate. Teeth 6 to 11 dip into the coating whilst teeth 2 to 5 do not touch the material. The measuring result is the mean...
