Features: Basic Functions: it can measure the non-metallic coating thickness(such as paint, film, etc.) of metal substrate surface quickly and accurately. Car/User Dual Modes: you can measure coating thickness of substrate material for calibration. And the car mode can be used without calibration, it measures coating thickness of 3 substrate materials(iron, aluminum and zinc), suitable for measuring the thickness of car. 3 Measurement Modes Switchable: Single measurement(SNG), continuous measurement(CTN) and difference value measurement(DIF) available, easy to switch by pressing the MODE button. 3 Calibration Ways Under User Mode: including zero calibration, two-point calibration and basic calibration. Metric and Imperial Measuring Units: short press the UNIT button to switch between mm(metric) and mil(imperial). Wide Applications: it is widely used in the inspection field of automobile manufacturing, metal processing industry, chemical industry, commodity inspection, etc. Specifications: Material: ABS Unit: mm, mil Measurement Range: 0~1.80mm/0~71.0mil Car Mode Resolution: 0.05mm/2mil User Mode Resolution: 0.01mm/1mil Measurement Error: 0.1mm Minimum Diameter of Substrate: 50mm Minimum Thickness of Substrate: 0.5mm Temperature Range: 18~30 Work Humidity Range: 10~80%RH Calibration Coating Film: 0.05/0.10/0.25/0.50/1.00/2.00mm Power Supply: 2 * 1.5V AAA battery (NOT included) Item Size: 105 * 62 * 30.5mm / 4.13 * 2.44 * 1.20in Item Weight: 57g / 2.03oz Package Weight: 109g / 3.86oz Package Size: 20 * 15.5 * 7.5cm / 7.87 * 6.10 * 2.95in Packing List: 1 * Thickness Gauge 6 * Calibration Coating Film 1 * Manual (English)
