Measuring Clinometer 90 Degree Ruler Digital angle meter that can measure or set angles, check relative angles, and function as a digital multitool. Magnetic base allows secure attachment to ferromagnetic surfaces such as conduits, pipes, saw blades, exhaust vents, and other metal surfaces, enabling hands operation on the workpiece surface under test. Application range Wood processing: precise cutting of wood corners Automotive : precise control of tire assembly angle Machine tool processing: precise positioning of machine tool working angle and rotation angle of boom Digital gauge: visibility invertedcontrast display improves readability in dimly lit work environments Use scenarios In a woodworking , align and set mitre angles for corner joints with confidence. In automotive , set the correct tire assembly angle to ensure proper alignment. In a machine , position a tool and set the rotation angle of a boom for accurate machining.
