Applications: Coating thickness gauge is a kind of portable measuring instrument, can take fast, intact, precise measurement of coating thickness. It can not only be used in engineering field, laboratories, but also meet the demand of multiple measuring by using different probes. It is used widely in manufacturing, metal processing industry, chemical industry, commodity inspection field, etc. As an essential instrument in material protection industry. The F probes measure the thickness of non-magnetic materials on magnetic materials. The N probes measure the thickness of non-conductive coatings on non-magnetic metals. Features: * Two principles: Magnetic Induction and Eddy Current. * Two measurement mode: Single and Continuous. * Metric/imperial system selectable. * Manual or automatic power off. * Automatic memory of calibration value,  and automatic recognize the substrate. * Operation process have buzzing reminder. * Integral Type have better stability and repeatability. * Separate Type can provide several types of probes,  measure can be more flexibility. * Use RS-232 data output to connect with PC. * Provide Bluetooth data output choice Principle& 65306;       Principles    Applications    Examples        F Type Magnetic Induction (Iron Base)    Measure the thickness of non-magnetic materials on magnetic materials    Galvanizing layer, lacquer layer, porcelain enamel layer, phosphide layer, copper tile, aluminium tile, some alloy tile, paper etc        NF Type Eddy Current (Aluminium Base)    Measure the thickness of non-conductive coatings on non-magnetic metals    Anodizing, varnish, paint, enamel, plastic coatings, powder, etc. Applied to aluminum, brass, non-magnetic stainless steel, etc
