Magnetic angle measuring instrument: a strong magnet at the bottom keeps the device securely in place on metal surfaces, workbenches, circular saw blades, or other metal surfaces. The magnetic functionality provides reliable measurement, cutting, and leveling support in woodworking and furniture construction. Digital protractor: measurement range of 4 × 90 degrees and powered by a battery (not included) for checking installation angles and angle leveling. Its small, portable size makes it easy to carry. Portable and compact design: lightweight and designed to fit into tight spaces, making it suitable for precision machinery and other enclosed areas. Zero and hold functions with a builtin level: press the zero button to set the relative zero angle on any reference plane. Shortpress the HOLD switch to lock the current measurement value on the display. The includes a precision bubble vial for leveling work without the need for batteries. Applications and practicality: Cabinet and furniture assembly: align frames, doors, and shelves with reliable magnetic holding and precise angle readings. Installation and leveling tasks in tight spaces: check and set angles for machinery setups or interior installations where space is limited. General leveling and angle reference in woodworking and metalworking projects, where quick reference angles and stable positioning improve accuracy.
