Digital Angle Ruler Protractor Ruler with Bubble Level Digital Goniometer 230mm 360° Angle Gauges with Vertical and Horizontal Circle Bubble Level, LCD Screen, Dual Scale Ruler

[360° Measurement and Data Lock] This protractor measures inside and outside angles through 360° and allows conversion between degrees and degrees/minutes. It features a lock button and a reset button. To lock the data, press the lock button. (Rotating the button only loosens or tightens the angle; it does not lock it completely.)

[4-in-1 Multifunctional Digital Protractor]: This product integrates a protractor, level, circle level, and ruler. It uses three bubble levels for calibration, allowing you to measure angles more accurately. (Note: This is not a digital level; the LCD screen does not display any numerical values. It only indicates whether an object is tilted.)

[Large LCD Screen and Auto Shut-Off]: This angle protractor features a large LCD screen for quick data reading. The digital protractor automatically shuts off after 5 minutes of inactivity to conserve power. It also features a reset button that allows you to reset it to any position, making it suitable for measuring both absolute and relative angles. 【Premium Materials & Portable Design】: The thicker and wider body of the ruler is made of high-strength fiberglass-reinforced nylon. This material is extremely durable, wear-resistant, non-deformable, and scratch-resistant, while also being lightweight and long-lasting. Its compact 230mm size makes it easy to use and carry. A hanging hole makes it easy to store.

【Numerous Applications】: This angle measuring tool is widely used in woodworking, architectural decoration, schools, home renovation, and machining (especially for setting the angles of circular saws, miter saws, band saws, etc.).
