Ideal for use in the laboratory, on the production line or the construction site, calibration foils or 'shims' are the most convenient way of creating a coating thickness standard on your substrate material or form. The ideal method for adjusting the calibration of your coating thickness gauge to ensure the greatest possible accuracy.

In some cases, however, it may be difficult, or impractical to obtain an uncoated substrate. For this reason Elcometer have provided a range of Zero Test Plates. These test plates, when used in conjunction with a set of foils,are ideal to test a coating thickness gauge's functionality and calibration.
