25-50mm Micrometer - Blue Standard Outside Micrometer Screw Micrometer

1、The measurement exterior is made of carbon steel, which is resistant to wear and deformation, and the measurement is more accurate. 2、The measuring range is 25‑50mm, which is a more precise tool for measuring length than vernier calipers. 3、Using laser engraving design, the scale standard reading is clear, and the accuracy of 0.01mm is guaranteed. 4、The micrometer has a glossy body and is stable and unimpeded when sliding on the worktable, ensuring stable measurement and improving efficiency. 5、The outside micrometer is suitable for measuring small grooves, such as drill bits, vertical milling cutters and other diameters and clock gears.Item Type: Micrometer Range: Approx. 25-50mm / 1-2in Material: Carbon Steel Resolution: 0.01mm Product Error: ±0.04mm Scale Technology: Laser scale Measurement 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. , The reading should be read to one-tenth of the minimum degree. 1 x Micrometer 1 x Wrench 1 x Gauge Block
