Specification: Item Type: Digital Angle Finder Material: ABS Capacity: 400mAh (Single Battery Capacity) Magnet: Strong magnetic force on the bottom, can be adsorbed on the of the measured object for measurement under adsorption state Description Multifunction: This digital angle finder offers a measuring range of 4x90° or 2x180° with an accuracy of ±0.1° and a resolution of 0.05°. It features point setting (relative or absolute measurement), data hold, reading function, and 4 measurement units (in, ft, mm, m). Application: It can be used to set or check the relative angles between surfaces, and can also be used as a true digital in narrow Spaces. Measure Range: The box can measure angles from completely horizontal (0°) to completely vertical (90°). The 180 degree measurement range offers flexibility and versatility for all around inclination measurements in various scenarios. Convenient Power Management: Equipped with a 400mAh rechargeable battery and Type C charging port, this angle measuring tool includes a low power indicator and automatically shut down when the battery power is low. Magnetic Base: The built in strong magnets on the base allow secure attachment to any ferrous , enabling stable measurements in tight spaces. The electronic bubble function quickly identifies tilt direction for efficient workflow. Package List: 1 x Digital Angle Finder 1 x Data Cable
