1. Product Type: Coating Thickness Gauge 2. Material: ABS 3. Weight: Approximately 107g / 3.8oz 4. Product Dimensions: Approximately 12.2x5x2.2cm / 4.8x2.0x0.9 inches 5. Measuring Range: 0 - 2000UM 6. Measuring Accuracy: ±(3% + 1UM) 7. Battery Type: 2 x AAA (batteries not included) 8. Packaging List: - 1 x Coating Thickness Gauge - 7 x Calibration Plates - 1 x English Manual 9. Convenience: It is a highly accurate and compact instrument for quickly and accurately measuring the thickness of coatings or platings on all metal surfaces. Simply place it on the test surface and it will automatically calculate. 10. Accuracy: Zero Calibration. To improve test accuracy, it is recommended to calibrate the instrument to zero. Press and hold until you hear a beep and the zero scale on the screen flashes. 11. Easy to Operate: Place the probe vertically and quickly on the bare surface of the substrate to be tested. When you hear a beep and the screen shows O, lift the probe at least 2 cm away from the substrate and reset to zero once. 12. Powerful Function: It can measure the thickness of paint, but more importantly, this paint coating thickness gauge can detect problems that may not be visible to the naked eye. 13. Wide Applications: This device can be used to measure the average thickness of paint on automobile bodies, and is applicable to manufacturing, metal processing, chemical industry, commodity inspection, laboratories, and workshops.
