Digital Angle Ruler with LCD, 400mm Stainless Steel

Accurate angle and length measurements in one reliable tool.

This digital angle ruler combines a stainless steel rule with an electronic protractor, giving you precise angle and length readings in a single compact device. The 400 mm stainless steel arms provide clear, durable graduations for linear measurement, while the integrated LCD screen displays angle readings for quick, confident work on site or in the workshop.

Designed for woodworking, construction, metalworking, and engineering tasks, this tool measures angles across a full 0-360° range. The digital display offers a resolution of 0.1° with an accuracy of ±0.3°, helping reduce measurement errors on miters, bevels, joints, and layouts. Simple push-button controls let you power the device on or off, reset to zero at any position, and lock the current reading when needed. An auto power-off function after approximately 6 minutes of inactivity helps conserve battery life (CR2032 3V lithium battery, not included).

Why It's a Smart Choice

• Two tools in one - Functions as both a 400 mm stainless steel ruler and a digital protractor, reducing the need to carry multiple instruments.
• Clear, fast readings - LCD display with 0.1° resolution and ±0.3° accuracy supports precise setup and inspection of angles.
• Flexible 360° rotation - Fully rotating arms and a lock function allow easy measurement of internal, external, and reverse angles in tight or awkward spaces.

FAQ

Q: What is the measuring range of this digital angle ruler?
A: It measures angles from 0° to 360° with a resolution of 0.1° and an accuracy of approximately ±0.3°.

Q: What battery does it use?
A: The tool uses one CR2032 3V lithium coin cell battery (not included).

Q: Can I reset the angle to zero at any position?
A: Yes. The zero function allows you to set a new reference angle at any position for relative measurements.

Q: Is it suitable for professional use on site?
A: Yes. The stainless steel construction, digital readout, and 360° rotation make it suitable for professional woodworking, construction, and engineering applications within the specified operating conditions (0-50°C, <85% RH).

Q: What is included in the package?
A: The package contains 1 x Digital Angle Ruler and 1 x User Manual.
