Features: LM320C Inclinometer delivers ±0.05° resolution and ±0.2° accuracy for precise angles measurement across ±90° ranges, featuring auto shutdown and triple magnetic base for secure attachment on metal surfaces. Built with impacts resistant ABS materials (50% more sturdy than standard plastic), this angles finder combines three sided magnetic adhesions, flipping screen display, and angles hold function for versatile operations. Essential for engineers, construction crews, and craft enthusiasts requiring professional grades accuracy in mechanical alignment, structural inspections, or home renovation projects. Optimized for challenging environments like construction site, outdoor surveys, and confined spaces where stable fixation and clear visibility are critical for error resistant measurements. Its 24 hour battery efficiency and solid design ensures uninterrupted performances in extreme conditions, while the touch interfaces simplifies complex angles tracking tasks.
