Elcometer 3230 Wet Film Wheels

The Elcometer 3230 Wet Film Wheel is a high precision, accurate and easy to use instrument which consists of a set of three wheels. The central wheel is of a smaller diameter and is eccentric relative to the two outer wheels. By rolling the gauge through a wet coating, the centre wheel eventually touches the film. This point on the scale indicates the thickness. A convenient mounting handle for the wheel is available in two lengths; 15cm ( 6” ) & 50cm ( 19” ) ; please order separately. When the volume to solids ratio of the coating is known ( generally found on the product data sheet supplied by the manufacturer) , the wet film thickness can be used to predict the dry film thickness. Several measurement ranges between 0 to 25µ m and 0 to 3000µ m ( 0 to 1mil and 0 to 40mils) are available. Continuous scale produces ± 5% measurement accuracy Suitable for flat and curved surfaces
