Coating Thickness Knife Tester | TPN-2808

Coating Thickness Knife – Overview Coating Thickness Knife Tester TPN-2808 (Paint Inspection Gauge) is designed to measure the thickness of both single and multiple-layer coatings on both metallic and non-metallic surfaces. The operation principle is based on the local cut (notch) of the coating at the tested place of an object with the following thickness measurement of this coating. The thickness of the coating is determined by the width of the notch, which is possible because of the special form cutter of the instrument. The measurement is performed by any portable measuring microscope with a suitable measuring range and discreteness. Coating Thickness Knife Tester TPN-2808 (Paint Inspection Gauge) complies with ISO 2808, ASTM B 4138, DIN EN 1071-2. Coating Thickness Knife – Feature Instrument allows users to determine the thickness of each layer individually for multilayer coatings.
