These credit card-sized (2.25′′ x 3.25′′) inexpensive, lightweight aluminum notch-type gauges contain a silk screened KTA logo and contact information, and are used measure the thickness of the wet paint film immediately after application. The gauge is placed squarely on freshly coated surface, withdrawn, and the wet coating thickness is read directly from the wetted steps (the highest wetted step indicates the wet film thickness). Measurements can be made in mils on one side of the gauge (1-80 mils) or in micrometers (microns) on the opposite side of the gauge (25-2032 microns). Conforms to ASTM D713 and D4414. Made in the USA.
