Usually the product should take about 6--13 business days to arrive your hand after your payment is confirmed Technical Parameter: Measuring range: 0~100um. 0-100µm accuracy:<3µm Product Description The Wheel is a high precision, accurate instrument which is easy to use. 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.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.
