Features: 1Wide Measuring Range: 360 (4 x 90) measuring range digital angle finder with an accuracy of 90, 0.2. Switching angle and slope at the touch of a button with a resolution of 0.01 degrees, this digital goniometer will provide you with the detailed information you need for CAD or design purposes. With a true accuracy of plus or minus 0.2, the most important factor in the accuracy of the digital goniometer is that it does not lose its accuracy over time. 2Magnetised Base: The digital protractor has a robust and stable magnetised base that allows you to attach the digital protractor directly to any ferrous metal surface, even curved surfaces. The protractor is housed in a robust, thick plastic case that resists damage from dropping or banging around 3LCD Display: The upgraded LCD display angle gauge has a high visibility inverse contrast, making it easier and clearer to read values even when working at night and easier to read at small angles than other displays. The values on the horizontal box display are automatically reversed to fit the eye for easy reading. 4Easy to Carry: The digital protractor has a portable size, making it easy to carry and work with other measuring tools to work in tight places and extend the measuring range. 5Wide Application: This digital inclinometer is an essential tool for use in commercial and residential projects, which can be used in decorative, carpentry, construction, masonry, mechanical and automotive applications. For example, you can use this angle gauge when operating a table saw or miter saw.
