High-Precision Digital Angle Gauge | 360° Multifunctional Universal Protractor | 200mm Measuring Tool for Carpentry, Renovation, and Drafting

Say goodbye to guesswork—read measurements at a glance! This professional-grade electronic protractor is designed specifically for carpenters, contractors, designers, and students. With a full measurement range of 0–360°, a high-definition digital display that provides real-time feedback, and support for data lock and relative zeroing, every angle measurement is precise, intuitive, and efficient. With just one tool, you can measure interior and exterior angles, measure lengths, and draw lines.

Product Details (Long Description)
📏 Precision & Clarity
Do traditional protractors have slow readings and high error rates? This digital angle ruler features a large, high-definition LCD screen that displays angle values in real time (such as 90.0° and 60.0° shown in the image), ensuring clear readability even in low-light conditions on construction sites or in workshops. With a full measurement range of 0–360°, it measures both interior and exterior angles instantly upon contact, completely eliminating errors caused by visual estimation.

🛠️ Four Core Features: Professional Tools That Understand Your Needs (Smart Features)
One-Touch Zero (ZERO): Supports both absolute and relative measurements. Briefly press the ZERO button with the ruler closed to reset to zero, enabling precise angle difference measurements (e.g., reference surface at 30°, target surface displays 60°).

Data Hold (HOLD): When measuring in tight spaces or corners with obstructed views, press the HOLD button to lock the screen data. You can then step back to read the measurement at your leisure—no more worrying about missing a reading.

Adjustable Tension: The unique rotating locking knob features moderate damping. It allows for flexible angle adjustment while locking the protractor in place during measurement, ensuring stable readings without shifting.

Flat Bottom: The bottom of the ruler features a flat, non-protruding design, allowing it to rest extremely steadily on a tabletop or workpiece and ensuring high-precision measurements.

📐 One Ruler, Multiple Uses—Covering All Scenarios (Versatility)
Metric and Imperial Dual Scales: The ruler is marked with both metric (mm) and imperial (inch) scales, with a maximum range of 0–200 mm, meeting measurement needs across various scenarios.

Suitable for Multiple Scenarios:

🏠 Home Renovation and Room Measurement: Precisely measure wall corners, baseboards, and inside and outside corners.

✏️ Design and Drafting: Lay out blueprints, quickly locate angles, and assist with drawing lines.

🪚 Woodworking: Precisely control angles for furniture assembly and wood cutting.

🎓 Student Angle Measurement: A great tool for geometry and technical drawing.

🔋 Long-Lasting Battery Life, Safe and Hassle-Free (Power & Durability)
Direct Type-C lithium-ion charging design (some batches include a complimentary CR2032 button cell battery). Say goodbye to the hassle of frequent battery changes—charge on the go and enjoy long-lasting battery life. For added convenience, it features an auto-shutdown function that automatically puts the device into sleep mode after a few minutes of inactivity, saving power and ensuring safety.
