Checkline 3000PRO [3000PRO-F] Coating Thickness Gauge with Ferrous Probe 0 - 60.00 mils / 0 - 1500 microns. The new Check-Line 3000PRO Series coating thickness gauge is a multifunctional fully menu driven gauge for fast, professional and precise coating thickness measurement for: paint and electroplated coatings on iron and steel; paint and anodizing coatings on non-ferrous metals and on austenitic stainless steels.  The user will select one or more probes best suited for their application to connect to the 3000PRO gauge as all the probes are interchangeable and their internal calibration is stored within a small microchip inside the probe connector housing.
