Rolling Wheel Wet Film Thickness Gauge (0-200 µm)

The gauge consists of an eccentric inner wheel supported by two large outer concentric wheels. At a specific point, the inner wheel touches and picks up the wet film when the gauge is rolled on the coated surface. The critical clearance may be read on a rotating scale. The gauge's body and the center holder are made of high-grade stainless steel. The scale value is cast on 1 side. The wheel is a high precision, the accurate instrument which is easy to use. The central wheel is of a smaller diameter and is eccentric relative to the two outer wheels. The center wheel eventually touches the film by rolling the gauge through a wet coating. This point on the scale indicates the thickness. When the volume-to-solids ratio of the layer is known (generally found on the product datasheet supplied by the manufacturer), the wet film thickness can be used to predict the dry film thickness.

• The Wheel Gauge uses the wheel rail eccentric wheel scale to get the wet film thickness, which is expressed in μm. It is suitable for measuring the wet film thickness of paint.
• A measuring tool for measuring the wet film thickness of paints, varnishes, etc. The thickness gauge can be measured not only on a flat substrate, but also on a curved substrate with high accuracy.
• It is mainly used to gauge the thickness of wet film on the painted surface and can estimate the relative thickness when it is dry.
• The instrument is under international standards ISO2808-1974.
• It can not only be used on flat substrates but also be used on curved substrates.
