INSIZE 3353-100 Digital Disk Micrometer/Snap Gauge 75-100 mm

The INSIZE 3353-100 digital disk micrometer/snap gauge measures 75-100 mm/3-3.95 in to an accuracy of 5 µm, with 1 µm repeatability and 5 µm parallelism, for checking the root tangent length of gear teeth. Its absolute encoder holds the reading after power-off, and resolution can be switched between 0.0002 mm, 0.001 mm and 0.01 mm. One turn of the sleeve feeds the spindle 5 mm without affecting accuracy, and the retract fork pulls it back 3 mm. It runs on a rechargeable battery for 24 hours of continuous use and comes with gauge blocks for zero setting.
