1、Using high‑definition LCD display screen, the measurement results are clear at a glance 2、The use of fine‑tuning large ratchet is more convenient and faster, durable to use 3、The probe is made of cemented carbide material, which makes the product more wear‑resistant 4、Ergonomic design, simple and convenient to operate, long‑term use will not be easy to fatigue 5、The measuring range is 0-25mm with 0.001mm accuracy, which can provide accurate readings 1 x Battery Cover Opener 1 x Digital Micrometer  Item Type: Digital Micrometer Measuring Range: Approx. 0 ~ 25mm / 0 ~ 1inAccuracy: 0.001mmHow 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%
