Feature:1. Using highdefinition LCD display screen, the measurement results are clear at a glance2. The use of finetuning large ratchet is more convenient and faster, durable to use3. The probe is made of cemented carbide material, which makes the product more wearresistant4. Ergonomic design, simple and convenient to operate, longterm use will not be easy to fatigue5. The measuring range is 0-25mm with 0.001mm accuracy, which can provide accurate readingsSpecification:Item Type: Digital Micrometer Measuring Range: Approx. 0 - 25mm or 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 can2. During use, it is possible to avoid exposure to dusty places, avoid sunlight, ultraviolet rays and high temperature radiation3. Do not put the micrometer on a magnetic object, the workpiece needs to be measured after demagnetization4. You can scrub the measuring surface with gasoline5. Operating Temperature: 0-40 Operating Temperature: 80 percent .Package List:1 x Battery Cover Opener 1 x Digital Micrometer
