Digital Angle Ruler with LCD, 400 mm Stainless Steel

Measure angles and lengths accurately with one tool in hand.

This digital angle ruler joins a stainless steel rule with an electronic protractor. The 400 mm stainless steel arms carry clear graduations for length, while the LCD shows angle readings for quick work on site or at the bench. It reads angles across a full 0-360 degree range, with a resolution of 0.1 degree and accuracy of plus-minus 0.3 degree, which helps keep miters, bevels, and joints on target.

Why we picked it

• Two tools in one - A 400 mm stainless steel ruler and a digital protractor, so you carry less.
• Clear readings - The LCD shows 0.1-degree resolution and plus-minus 0.3-degree accuracy for confident setup.
• Full rotation - Arms rotate 360 degrees with a lock, so you can catch inside, outside, and reverse angles in tight spots.

Good to know

Range is 0 to 360 degrees at 0.1-degree resolution and about plus-minus 0.3-degree accuracy. Buttons handle power, zero-at-any-position, and reading lock. It powers off automatically after about 6 minutes idle to save the CR2032 3V lithium battery (not included). Rated for 0-50 degrees C and under 85% RH. The box holds one digital angle ruler and one user manual.

Common questions

Q: What is the measuring range?
A: 0 to 360 degrees, with 0.1-degree resolution and roughly plus-minus 0.3-degree accuracy.

Q: What battery does it use?
A: One CR2032 3V lithium coin cell, not included.

Q: Can I zero the angle anywhere?
A: Yes. The zero function sets a new reference angle at any position for relative readings.

Q: Is it fit for professional site use?
A: Yes. The stainless steel build, digital readout, and 360-degree rotation suit woodworking, construction, and engineering within 0-50 degrees C and under 85% RH.
