This portable coating thickness gauge measure the thickness of non-magnetic coatings on magnetic or non-magnetic metal substrates with choice of remote probe. It has large, easy-to-read LCD provides exact measured readings and μm/mil conversion switch. Includes hard carrying case and batteries (order F or N probe separately). F probe measures the thickness of non-magnetic coatings on magnetic metal substrates; N probe measures the thickness of non-magnetic coatings on non-magnetic metal substrates.
