Features:This product has built-in magnetic induction and dual vortex principle probe, can automatically identify the measured metal substrate, only needs to be placed on the measured surface, can automatically calculate the coating thickness.With digital LCD backlight display, this car paint thickness gauge can read the data clearly in night or dark environment.The unit of measurement can be switched between mm and mil to facilitate different measurement requirements.When measuring paint thickness, the tester should be perpendicular to the testing surface at 90.This portable coating thickness gauge can measure the thickness of a non-metallic coating (such as paint, film, etc.) on a metal substrate quickly, non-destructively and accurately.It is mainly used to measure the thickness of vehicle surface paint and other coatings.Measuring StepStep 1. Prepare the parts to be tested.2nd step. Keep away from the metal object at least 2cm, press the switch key to turn on. Note: It is suggested that the instrument be zeroed in reference to zero calibration before testing.Step 3. The probe is placed vertically and quickly on the surface to be measured until the drop is heard, and the measured value is displayed on the screen, then the probe is raised at least 2 cm from the part to be measured , and the next measurement can be performed. Note: If the auto-off function is enabled and no operation is performed within 3 minutes, the instrument will automatically turn off.Features:Material: ABS Color: Orange, black (optional) Screen: horizontal, vertical (optional) Measuring range: 0~2000um Accuracy: (3%+1um) Resolution: 0um ~ 99.9um (0.1um) 100um ~ 999um (1um) > 1000um (0.01mm) Zero Calibration: Support Statistics: Average, minimum, maximum, number Unit:um,mm,mils Minimum convex radian: 5 mm Radian concave minimum: 25 mm Minimum surface measured: Diameter 20 mm Minimum substrate thickness: 0.2 mm Diameter 20 mm Maximum measuring speed: 2 readings per second Power: 2 x 1.5V 7 batteries (not included) Operating environment Temperature: 0 ~ 50C 20 ~ 90% RH (non-condensing) Storage environment Temperature: -10^60C 20^90% RH (non-condensing) Size: 113mmX53mmX24mm weight: 80g Packing List:1 * thickness gauge 1 * calibration piece 1 * Instructions
