Key benefits - Large dial with a high quality mirror and hardened surface for wear resistance. High light transmittance provides a bright, clear view. For accurate readings, view perpendicularly to the dial. - Sturdy safety base with elastic TPU foot pads. Waterproof and non-slip, preventing tilting or rolling for stable, reliable use. - Battery-free operation. Gravity acts on the spring to drive the force arm and rotate the pointer, delivering pure physical movement without power needs. - Durable mechanical scale with 8 mm tempered glass. High strength and resistant to breakage, with edge safety to avoid scratches around the arc. What to expect - Function and performance: an analog, spring-driven gauge that measures without batteries, offering straightforward, mechanical operation and durable readability. - Material and construction: large dial and glass scale designed for visibility; TPU feet provide grip and protection against slippage and moisture. - Readability and accuracy: clear readings when observed perpendicular to the dial; the mirror and glass work together to enhance visibility and durability. Specifications and compatibility - Mechanical scale uses 8 mm tempered glass for high strength and impact resistance. - Safety base includes elastic TPU foot pads for waterproofing, slip resistance, and stability. - Reading method is purely mechanical: gravity-driven movement of the spring forces the pointer to rotate. - No batteries or external power required. Use scenarios - Workshop or electronics bench: quickly check small component tolerances or assembly fit during precision projects, with reliable reads in any lighting. - DIY garage or home repairs: convenient, battery-free gauging on a stable surface for routine measurements and adjustments. - Repair shop or manufacturing side work: stable, durable gauge for repeatable readings on components that require careful handling and clear visibility.
