This portable lightweight coating thickness gage nondestructively measures the thickness of nonmagnetic coatings applied to ferrous substrates. The gage can be used with cylindrical parts and on the exterior of pipe, and can be used in any direction, even overhead. The gage is similar to Mikrotest III, except the dial retracts and stops automatically, minimizing operator error. The scale on Model Zn-Fe reveals the thickness of galvanizing in oz/ft2 rather than in mils or microns. The gage is sold complete with carrying pouch. Conforms to ASTM D7091 and SSPC PA2. Accuracy is +/- 5% of the measurement.
