Easy to Use: The digital level angle gauge features an ABS shell for lightweight and durable performance. It is powered by 2 AAA batteries (not included) and uses a simple onebutton interface for effortless measurements. Angle and Slope Precision: Provides accurate readings with easy conversion between angle and slope. You can switch between relative and absolute measurement modes at any hold point with straightforward controls. Battery Life Saver and Magnetic Support: Autopower off after 5 minutes of inactivity helps conserve energy. The builtin magnet allows stable adsorption onto measuring workpieces, streamlining measurement workflows. Versatile and Portable: Can be used with other measurement tools to extend range and improve accuracy. Its compact size makes it easy to carry and store. Practical use scenarios: Carpentry and cabinetry: level shelves, align doors, and install cabinets with consistent angles. Machinery setup and alignment: position jigs and fixtures accurately on work surfaces. Welding and metal fabrication: verify frame angles and ensure right angles during assembly. Key attributes at a glance: function (angle and slope measurements with conversion), compatibility (works with other measurement tools), size (portable and easy to store), material (ABS shell for durability), and performance (autopower off for energy efficiency and a magnetic attachment for stability).
