[Universal]: The bevel can be fully rotated in either direction, and can measure 360 angles (that is, tell the inner and outer angles), as well as the length (metric and imperial). [Precise measurement]: LCD display, electronic digital display, convenient angle detection, Accurate measurement, precise angle resolution: 0.05/3, accuracy: 0.05. Lightweight & Durable & LCD Display: The digital tilt ruler is thickened and widened with nylon glass, made of nylon fiberglass material, with high strength, good rigidity, wear resistance and no deformation. The protractor adopts a large-screen LCD display, which is clear and easy to read, so that you will no longer guess the angle and length when selecting the zero point.
