Film thickness plays an essential part in the use and testing of paints and coating materials.  The film thickness determines the appearance, durability and protective qualities.  Too thin a film results with inadequate protection of the substrate and too thick a film also has issues such as cracking, excessive drying time and poor finish.  

Wet film gauges are used to check freshly applied coatings and can be used to calculate the resulting dry film thickness.  If deviations have been detected they can be corrected immediately.  

Model 234: Wet Film Thickness Gauge.
• In accordance with ISO 2808, ASTM D1212, BS 3900 : C5
• Disc shaped instrument rolls over coating and picks up film once thickness of film equals the gap to the rims.
• Available in varying ranges up to 1500µm.

Model 333: Wet Film Thickness Gauge acc. to Rossman.
• In accordance with ISO 2808, BS 3900 : C5
