The digital internal micrometer from Mahr is a precise length measuring tool designed for the accurate measurement of internal dimensions in a range of 10 to 12 mm. It features a high-contrast digital display that allows for easy and direct reading of measurement results. Thanks to the innovative REFERENCE measuring system, the set zero position is retained even after the device is turned off, significantly simplifying operation. The lock function protects against accidental measurement errors by locking the control buttons. The internal micrometer is equipped with a self-centering measuring head, which has carbide measuring jaws starting from a diameter of 12 mm, while the measuring head from 40 mm is made of lightweight aluminum to reduce weight. The digital internal micrometer is battery-operated and comes with a CR2032 battery included.
