Features:It has the ability to measure the thickness of non magnetic coating (such as paint) on magnetic materials such as steel/iron, as well as the thickness of coating (such as paint) on non magnetic materials such as aluminum.Built in precision-probe, lithiums battery charging. Automatically detect substrate properties and detect coating thickness through electromagnetic induction and eddy-current effects.This instrument can non-destructive measure the thickness of the coating, with fast speed and high accuracy.Widely used in manufacturing, chemicals industry, automotive and other testing fields.Notice:1.Actual color may be slightly different from the image due to different light effect2.Please allow 1-3cm deviation due to manual measurementDescription:Measuring Range0-1400mAccuracy3%+2mResolution Ratio0.1mCalibrationZero point calibrationMulti-point calibrationUnitmmilMini Convex Curvature Radius5mmMini Concave Curvature Radius25mmMini Measurement Area Diameter20mmWork EnvironmentNo strong magnetic fieldWork Temperature-10 -+50 Humidity20% -90%RHBattery600mAh LithiumS batterySize115 x 48 x 18mmWeightAbout 83gData storage: SupportPuttys powder test: SupportRotatable screen: SupportAuto Power Off: SupportPacking list:CTG-20 coating thicknes gaugeFerrous calibration substrateNon-Ferrous calibration substrate,50/100/250/500/1000m calibration sheeUSB data cableUser manual
