Base for Secure Attachment This angle protractor includes a base that securely attaches to the measuring surface, enabling stable and repeatable angle measurement on a variety of workpieces. Data Hold for Easy Reading Equipped with a data hold function to lock the measured angle value, allowing easy reading and preventing drift during measurement. Angle and Slope Conversion The digital electronic protractor inclinometer provides easy conversion between angle and slope, increasing its versatility for tasks ranging from carpentry to engineering. Relative and Absolute Measurements Offers the ability to switch between relative and absolute measurements, giving you flexibility to capture readings with reference to a workpiece or to a fixed baseline. Use scenarios Carpentry and cabinetry: set precise miter angles for trim, doors, and cabinet frames. Metalworking and machining: align parts, check bevels, and verify tool setup on jigs and fixtures. Automotive or machine installations: verify orientations and slopes during installation and alignment tasks.
