【Two-in-one digital protractor function combination】: The combination of ruler and protractor is convenient for measurement. Works as a digital protractor and angle gauge at the same time to measure all angles. 【Universal】: The bevel can be fully rotated in both directions and can measure angles of 360° (ie internal and external angles) as well as lengths (metric and imperial). 【Precise measurement】: LCD screen, electronic digital display, detection Practical protractor, precise measurement, precise angle resolution: 0.05°/3°, accuracy: ±0.05°. 【Lightweight and durable and LCD screen】: The rule The digital bevel ruler is thickened and widened by a nylon glass ruler, which is made of high-speed nylon fiberglass material. high strength, good rigidity, wear resistance. Wear and no deformation. The protractor has a large, easy-to-read LCD screen. Read so you never have to guess angles and lengths again when selecting the zero point. 【Wide range of applications】: Widely used in woodworking
