Magnetic base for secure attachment This angle protractor uses a magnetic base to securely attach to the measuring surface, enabling convenient angle measurement on various workpieces. Switch between relative and absolute measurements The device can switch between relative and absolute angle readings, providing flexibility to capture accurate readings based on your reference. Angle and slope conversion The digital electronic protractor inclinometer supports easy conversion between angle and slope measurements, making it versatile for tasks from carpentry to engineering. Data hold for easy reading A data hold function locks the measured angle value for easy reading, preventing fluctuations from affecting your measurement. Use scenarios Woodworking and carpentry Use for setting bevels on miter saws, aligning jig setups, and verifying the angle accuracy of cut pieces. Cabinet installation and furniture making Ensure square frames, align panels, and transfer angles between components for precise assembly. General fabrication and engineering Measure and convert angles to slopes for roof pitches, machine setups, or dimensional layouts.
