The Handheld Electronic Thickness Gauge is a highly intelligent, sophisticated instrument used to quickly and accurately measure the thickness of coatings or platings on almost all kinds of metal surfaces. It not only shows the thickness of coating or plating, but also automatically recognizes the substrate. Fe represents magnetic metals, such as steel; NFe represents non-magnetic metals, such as aluminum, alloys and non-magnetic stainless steel. It is suitable for measuring various coatings or coatings, including non-magnetic coatings, ceramics, enamel, plastics, rubber coatings on magnetic substrates such as steel, non-ferrous metal coatings such as nickel and chromium, and anti-corrosion coatings in chemical and chemical industries. Non-conductive electroplating, plastic coating and anodic oxidation film on non-magnetic devices such as petroleum industry, aircraft, spacecraft, vehicles, household appliances, aluminum alloy doors and windows and other aluminum products, as well as conductive coating or only coating or plating Conductivity at least 3 times lower than the base material (eg chrome-plated copper) is sufficient. -Fe or NFe 2 in 1 - Automatic power off. - Flip display for easy reading in any condition and angle - Simultaneous display of 4 readings -Mini Coating Thickness Gauge -Model: RZ260FN -100% brand new -Low battery indicator - Range: 0-1250um; M, 0 - 50mil - Resolution: 1um /0.1mils - Accuracy: +/-(3%+2um) or +/-(3%+0.1mils) -Power supply: 1xAAA 1.5V battery (not included) -Package: glasses case, belt case -Size: 100*52*29mm - Weight: 68g (without battery) -Working temperature: 0~50C (+32~120F)
