Precision Digital Micrometer 0-1" with LCD Display - High Accuracy Measuring Tool for Machinists, Engineers & Metalworking - Perfect for Calibration, Quality Control & Workshop Measurements

Feature:1. The measuring surface of the micrometer is made of carbon steel, which is to abrasion and deformation, and the measurement is more accurate.2. The measuring range is 50‑75mm, and the accuracy can be 0.01mm. It is a very accurate and reliable measuring tool.3. The precise mechanical structure locking device makes the reading more intuitive and accurate.4. The micrometer has a glossy body and adopts laser scale technology, which makes it glossy when sliding on the object to measure.5. The outside micrometer is suitable for measuring small grooves, such as drill bits, vertical milling cutters and other diameters and clock gears.Specification:Item Type: MicrometerRange: Approx. 50-75mm / 2-3inMaterial: Carbon steelResolution: Approx. 0.01mmError: Approx. ±0.04mmScale Technology: Laser scaleMeasurement Type: Outer diameter measurementHow to use: 1. For zero calibration, ensure that the front edge of the micrometer cylinder is aligned with the horizontal engraved line, and the main axis scale is aligned with the zero scale of the micrometer cylinder. The first step to correct the degree is to ensure that the zero calibration is correct.2. When measuring an object, first rotate the ratchet to adjust the distance between the side drill and the side micro screw to be slightly larger than the size of the object, and put the object to be measured into it.3. Slowly rotate the ratchet until it clicks, and the reading starts. The click indicates that it has been locked, and it is not necessary to rotate it too hard, otherwise it will cause damage.4. First, read the graduation value of the scale line under the fixed casing with the end surface of the microtube as the guideline, and then use the horizontal line on the fixed casing as the reading guideline to read the graduation value on the movable scale
