Feature Convenient and Portable:The mini digital angle finder is small and light, making it convenient to carry and used, there are powerful built-in magnets on the angle gauge base which secures the attachment to any iron surface, applied to saw table, band saws, metal poles, round pipes etc quickly and easily. This angle gauge is specially useful for completing work on ladders, roofs or other dangerous locations. High Accuracy The accuracy of the angle gauge is 0.1, the measuring range is 360 (4*90), resolution of 0.1, The reading can be quickly stabilized, and the number will not change repeatedly. Absolute / Relative Angle Our inclinometer is suitable for measuring both absolute angle and relative angle, which makes this protractor to be easier and faster in daily applications and engineering applications. Multi-function The angle gauge is designed with large LCD Display, powerful magnet in the bast and upright display, which makes it much easier and clearer to read the values.
