1Using highdefinition LCD display screen, the measurement results are clear at a glance 2The use of finetuning large ratchet is more convenient and faster, durable to use 3The probe is made of cemented carbide material, which makes the product more wearresistant 4Ergonomic design, simple and convenient to operate, longterm use will not be easy to fatigue 5The measuring range is 0-25mm with 0.001mm accuracy, which can provide accurate readings Item Type: Digital MicrometerMeasuring 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% 1 x Battery Cover Opener 1 x Digital Micrometer
