The Elcometer 990 Calibration Foils and Zero Test plates are ideal for use in the laboratory, on the production line or on site. Calibration foils or 'shims' are the most convenient way of creating a coating thickness standard on the substrate material, surface finish or form. This is the ideal method for adjusting the calibration of the coating thickness gauge to ensure the greatest possible accuracy.

In some cases, it may be difficult or impractical to obtain an uncoated substrate. For this reason Elcometer provides 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.
