Features: Basic Functions: it can measure the thickness of the non- coatings e. Paint, zinc on steel, the thickness of the insulating coatings e. Paint on no-ferrous metals, and the no-ferrous metals coatings on insulating substrates.Dual Working Principle: dual technology features automatic selection of induction or eddy current measurement techniques. Four Calibrations: point calibration, 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, it will alarm you. USB Interface for PC Software: all the measured data can be uploaded to for data analysis. Other Features:, MAX, MIN, NO. DEV statistic display; Low, error indication; Delete 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: ABS Probe: Fe/NFe Working Principle: induction/Eddy current principle Minimum Curvature Radius: 1.5mm/3mm Diameter of Minimum Area: 7mm/5mm Basic Critical Thickness: 0.5mm/0.3mm Measuring : 01800µm Guaranteed Tolerance(of reading): 01000: ±(2.5%+2µm), 10001800: ±(3.5%) Resolution: 0100µm: 0.1µm, 1001000: 1µm, 10001800µm: 0.01µm Low : 0.1µm Operating Environment: 040? , 20%90%RH : 2 1.5V AAA (NOT included) Item Size: 113.5 54 27mm / 4.47 2.13 1.06in Item Weight: 185g / 6.52oz Package Weight: 816g / 28.80oz Package Size: 27.5 19 7.5cm / 10.83 7.48 2.95in Packing List: 1 Thickness Gauge 1 USB Cable 1 1 Calibration Iron 1 Calibration Aluminum 5 Calibration Coating Film 1 Carrying.
