Features:Basic Functions: it can measure the thickness of the non-magnetic coatings (e.g. paint, zinc) on steel, the thickness of the insulating coatings (e.g. paint) on no-ferrous metals, and the no-ferrous metals coatings on insulating substrates.Dual Working Principle: dual technology features automatic selection of magnetic induction or eddy current measurement techniques.Four Calibrations: zero point calibration, one point calibration, two points calibration and basic calibration, you can choose the more proper calibrate method according to the the condition or the thickness of measured surface.Direct Working and Group Working Two Modes: the DIR mode for a quickly and randomly measuring(the measured data are not saved after shutdown or working mode switching); the rest including 30 kinds of working mode, which can save 50 data of each mode(1500 totally).High and Low Alarm for all Working Modes: once the measured data exceed the preset range, it will alarm you.USB Interface for PC Software: all the measured data can be uploaded to computer for data analysis.Other Features: AGV, MAX, MIN, NO., and S.DEV statistic display; Low battery, error indication; Delete single readings and all group readings easily; Automatic shutdown, etc.Wide Applications: it is widely used in the inspection field of automobile manufacturing, metal processing industry, chemical industry, commodity inspection, etc.Specifications:Material: ABSSensor Probe: FeNFeWorking Principle: Magnetic inductionEddy current principleMinimum Curvature Radius: 1.5mm3mmDiameter of Minimum Area: 7mm5mmBasic Critical Thickness: 0.5mm0.3mmMeasuring Range: 0~1800mGuaranteed Tolerance(of reading): 0~1000: (2.5%+2m), 1000~1800: (3.5%)Resolution: 0~100m: 0.1m, 100~1000: 1m, 1000~1800m: 0.01mLow Range Precision: 0.1mOperating Environment: 0~40(32~104), 20%~90%RHPower Supply: 2 * 1.5V AAA battery (NOT included)Item Size: 113.5 * 54 * 27mm 4.47 * 2.13 * 1.06inItem Weight: 185g 6.52ozPackage Weight: 816g 28.80ozPackage Size: 27.5 * 19 * 7.5cm 10.83 * 7.48 * 2.95inPacking List:1 * Thickness Gauge1 * USB Cable1 * CD1 * Calibration Iron1 * Calibration Aluminum5 * Calibration Coating Film1 * Carrying Case
