Precision Angle and Slope Measurement Achieve precise measurements with a resolution sensor accurate to 0.1 degrees. The digital display provides instant readouts for quick alignment in construction, engineering, and DIY projects, helping you achieve angles and slopes every time. Hands Magnetic Operation Builtin strong magnets securely attach to metal surfaces, allowing stable measurements on pipes, beams, and machinery. This design frees both hands for adjustments while maintaining consistent contact with the measured surface. Versatile MultiFunction Modes Switch effortlessly between absolute angle, relative difference, and slope percentage with one button. The unit conversion feature displays results in degrees, percent grade, or mm/m to suit different project requirements. Efficient Power Management A 400 mAh lithium battery supports 30 hours of continuous use. Auto poweroff after 5 minutes of inactivity conserves battery life, while TypeC charging enables quick recharging. The automatic backlight enhances visibility in lowlight conditions. Applications and scenarios Construction framing and roofing: Attach to metal studs or beams to verify absolute angles and ensure precise slope for accurate joins and alignments. Machinery and piping installation: Use magnetic attachment to measure angles and slope on equipment, conveyors, and piping with hands stability. DIY projects and jig setup: Check joint angles, set up jigs, and confirm slope requirements for woodworking, metalworking, and home improvement tasks.
