Guanglu Digital Caliper 150mm

The professional industrial-grade stainless steel digital caliper featuring 0.01mm high-precision readouts, an absolute origin sensor system, and an eco-friendly 3V lithium power core for high-end watchmaking, jewelry design, and laboratory validation. Securing reproducible tolerances on precious metal components, watch case crystals, or micro-machined dental molds requires unyielding metrology hardware. The Guanglu 150mm Digital Caliper delivers premium operational reliability. Built with precision-lapped measuring faces and a dedicated conversion chip, this instrument allows technicians to instantly track external, internal, depth, and step parameters with zero tracking errors.

Advantages

• Premium All-Stainless Steel Metallurgy: The heavy-duty main beam, slide housing, and measuring jaws are precision-milled from premium hardened stainless steel, preventing bending distortion and securing perfect jaw parallelism over a lifetime of bench wear.

• Absolute Origin Metrology System: Advanced electronic memory chips retain the reference zero-point even after the display screen auto-shuts down. This prevents the need to constantly re-zero the tool, eliminating calculation or visual tracking mistakes.

• Eco-Friendly High-Capacity 3V Lithium Battery: Powered by an industrial-grade 3V CR2032 lithium battery cell, providing significantly longer operational lifespans and more consistent power delivery over standard alkaline setups.

• Precision-Ground 4-Way Diagnostic Architecture: Expertly machined measuring surfaces provide complete layout flexibility across four functional dimensions:

  1. External Measuring Jaws: For checking outside sheet stock thicknesses, loose gem tables, and watch case boundaries.

  2. Internal Knife-Edge Blades: Designed to smoothly access ring shanks, narrow slots, tubing interiors, and bracelet buckle rails.

  3. Slender Depth Stem Rod: Slides cleanly from the beam tail to cross-verify blind holes, inner sleeves, and case recesses.

  4. Parallel Step Reference Faces: The rear stepped edges of the slider block allow for precise vertical step tracking along parallel component tiers.

• Instant Unit Translation Reset: A dedicated button toggles between metric millimeters and imperial decimal inches at any positioning along the bar beam, simplifying international size conversions.

• Relative vs. Absolute Zero Reset: Features a standalone ZERO reset toggle at any slider intersection, allowing for instant comparative differential measurements between sample models.
