1. Magnetic Digital Protractor: Featuring a powerful magnetic attachment for secure placement on metal surfaces, this tool enables hands angle measurement with stable performance across a range of tasks. 2. Accurate Angle Measurement: Delivering precise readings with 0.05° resolution and ±1° accuracy, this inclinometer supports both relative and absolute measurement modes for reliable slope and angle data. 3. Dual Measurement Modes: Switch effortlessly between angle degrees and slope percentages, making this digital level ideal for carpentry, construction, and general home improvement projects requiring versatile format options. 4. Data Lock Function: Utilize the data lock to freeze measurements on the clear display, allowing easy reading and recording without interrupting your workflow or losing important angle information. 5. Practical Use Scenarios: Cabinet and furniture installation: attach to metal frames with the magnetic attachment for hands measurement; use the locked display to transfer precise angles to cuts. Framing and level checks: place on metal studs to verify wall plumb or floor slope; switch between degrees and percent as you plan joints and alignments. DIY mounting and alignment: measure shelf and picture frame angles quickly with both hands , then lock readings for documentation.
