Item Type: Digital Micrometer Measuring Range: Approx. 0 ~ 25mm / 0 ~ 1in Accuracy: 0.001mm How to Use: 1. Because the micrometer is a accuracy measuring tool, it is prevented from falling, collision, etc., and loss of accuracy during use and storage. Otherwise, you need to re-check the calibration before you can 2. During use, it is possible to avoid exposure to dusty places, avoid sunlight, ultraviolet rays and high temperature radiation 3. Do not put the micrometer on a magnetic object, the workpiece needs to be measured after demagnetization 4. You can scrub the measuring surface with gasoline 5. Operating Temperature: 0-40; Operating Temperature: 80% Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
