Dial Caliper

The professional-grade all-metal mechanical dial caliper featuring 0.02mm high-sensitivity resolution, an integrated dual-way shockproof gear mechanism, and premium chrome-plated finishing. When checking tolerances on machined jewelry blanks, internal bearing sleeves, or delicate watch crowns, reliance on battery-powered digital chips can create unexpected bench downtime. This Stainless Steel Dial Caliper offers a completely autonomous, ultra-reliable mechanical metrology solution. Outfitted with a finely ground rack-and-pinion transmission and an intuitive, clear-view dial, this analog gauge converts micro-movements fluidly into stable, highly precise readings.

Advantages

• Premium All-Stainless Steel Metallurgy: The entire caliper frame, main beam guide, and quantifying jaws are precision-crafted from high-quality stainless steel, delivering exceptional structural stiffness and long-term distortion-free tracking.

• Dual-Way Shockproof Gear Architecture: High-quality micro-gears are embedded securely into a robust, specialized shockproof indicator head. This advanced interior mechanics dampens sudden bench impacts and sudden slide shifts, ensuring a smooth, backlash-free needle sweep.

• Flawless Chrome-Plated Polish & Finish: Expertly machined with fine workmanship, the main beam undergoes a thorough satin chrome-plating phase. This treatment leaves a completely smooth surface finish without micro-burrs, reducing thumb sliding friction while eliminating harsh reflections under intense bench lamps.

• 0.02mm High-Sensitivity Analog Resolution: Provides crisp, dark graduation hashes on a bright dial face, calibrated to read down to an exact 0.02mm interval with a strict hardware accuracy tolerance of ±0.03mm.

• Smooth Thumb Slider with Lockdown Clamp: Outfitted with a knurled thumb adjustment screw-wheel for agile sliding control and an integrated top locking clamp to freeze data readings safely for multi-part comparison.
