Brass Caliper

The classic hand-held solid brass mechanical vernier caliper featuring an extended 100mm single-direction jaw alignment, non-magnetic physics, and dual metric/imperial graduation tracking for scratch-free field audits of precious gems and delicate jewelry artifacts. Measuring loose diamond parcels, soft crystal beads, or high-purity gold settings on the spot requires measuring tools that protect sensitive materials. This Solid Brass Mini Caliper delivers a completely autonomous, battery-free metrology solution. Formatted with an elongated, flat-surface single jaw architecture, this pocket-sized instrument naturally patinas over time, providing a smooth, scratch-free mechanical interface right at your appraisal desk or trade show booth.

Advantages

• Premium Non-Magnetic Solid Brass Construction: Machined completely from solid brass stock. This material is inherently non-magnetic and strong, acting as a protective cushion against soft gold, sterling silver, and mineral surfaces.

• Extended 100mm Measurement Reach: Engineered with a continuous slide capacity up to 100mm (4 inches), comfortably expanding beyond the limits of standard mini pocket sizers to check larger charms, broad plate dimensions, and thick wire stock.

• Dual Millimeter & Inch Scale Tracking: Features clear, stamped scale hashes registering metric millimeters along the lower slideway and fractional inches along the upper register, accommodating international design formats seamlessly.

• Ultra-Lightweight Pocket Geometry: Nesting comfortably flat within the palm of your hand, its ultra-slim profile slips easily into bench aprons, travel gear kits, or loupe storage bags for rapid field travel deployments.
