1. MAGNETIC ADSORPTION: This digital inclinometer attaches securely to metal surfaces via magnetic adsorption, enabling hands operation during measurements. Its strong magnetic base ensures stable positioning on any ferrous material, allowing for accurate readings without manual support. 2. DUAL MEASUREMENT MODES: Easily switch between relative and absolute measurement modes with a single button press. The relative mode lets you set custom reference points, while the absolute mode provides true horizontal/vertical measurements, making it versatile for various applications. 3. ANGLE AND TILT CONVERSION: This multifunctional digital protractor effortlessly converts between angle degrees and slope percentages. Ideal for construction, woodworking, automotive repairs, and other tasks requiring precise angle measurements. 4. DATA LOCK FUNCTION: The convenient data lock feature freezes readings on the clear digital display, allowing you to move the inclinometer from hardtosee positions while retaining measurements for easy recording and reference.
