Calotest Compact (CAT²c)

Calotest is designed to quickly characterize coating thickness. The CAT²c is widely used for analyzing coatings with thicknesses between 0.1 μm and 50 μm. The simple ball-cratering method offers a fast and accurate means of checking the thickness of any kind of coating, whether a single or multilayered stack. Typical examples include CVD, PVD, plasma spray coatings, anodic oxidation layers, chemical and galvanic deposits, polymers, paints and lacquers.
