Dimensions: 31.5 cm x 3.5 cm 2-in-1 Multifunctional Tool: Discover the perfect combination of a ruler and a protractor for simple and precise measurements. Use this tool as both a digital and a traditional protractor to measure all angles in the workshop. The digital angle gauge features laser-engraved metric and imperial measurements on the edge of the ruler, providing a clear and accurate digital display. It allows you to measure both angles and lengths, making it ideal for woodworking, construction, and drafting. High Precision: This digital angle ruler offers an accuracy of ±0.5 degrees. Its measuring range is from 0 to 360°, with an additional capacity from 0.00° to 999.9°. The folded length is 11 inches (300 mm), while its total length reaches 600 mm. It's an excellent choice for most projects, whether for home improvement, DIY projects, woodworking, decorating, or machining. Lightweight and Durable, LCD Screen: This digital angle finder, made of glass and thickened nylon, is constructed with high-strength nylon fiberglass material. It offers excellent rigidity, high wear resistance, and won't deform. When measuring an angle, the protractor features a large, easy-to-read LCD screen, so you no longer need to guess the angle or length. 360-Degree Inversion: This digital protractor tool features an inversion function. Simply place the angle finder gauge where you need to make your next cut, lock it in place with the knurled lock nut, and mark the position. You can then use a miter saw to make precise cuts. Furthermore, the display has a hold function that freezes the movement, ensuring accurate measurements. This saves you considerable time and effort.
