High precise digital thickness gauge with measurement range 0-2000UM. Requires calibration for accuracy. Multifunctional design: battery power indicator, 3-minute auto shutoff, and backlight on/off support. Statistical display function shows average, minimum, maximum, and number of data (up to 50, auto-updates with new data replacing old). Comes with aluminum base sheet and 6 calibration films (0.05mm, 0.25mm, 0.10mm, 0.50mm, 1.00mm, 2.00mm). Used for non-destructive measurement of coating thickness on metal surfaces, suitable for non-conductive coatings on metal and non-ferromagnetic coatings on ferromagnetic metals (e.g., automobile paint, metal parts coating). Widely applicable in manufacturing, metal processing, commercial inspection, laboratories, and workshops. Material: ABS, color as shown in the picture. Display: LCD backlight. Power: 2*1.5V AAA batteries (not included). Measurement accuracy: (3% +1UM). Operating temperature: -10 to 50℃. Item size: 85*40*30mm. Package includes: 1*Thickness Gauge, 6*Calibration Film, 1*Base Sheet, 1*Manual.
