Digital Carbon Fiber Vernier Caliper Gauge 150mm with Hard Plastic Case

Achieve fast, non-marring, high-precision measurements across engineering, 3D printing, jewelry making, and woodworking projects with the Digital Carbon Fiber Vernier Caliper Gauge 150mm (6-Inch) with Hard Protective Storage Case. Engineered from high-strength carbon fiber composite, this ultra-lightweight digital micrometer caliper delivers dependable accuracy without scratching delicate surfaces, conducting electrical currents, or weighing down your field toolkit.

Supplied in a heavy-duty, latching hard plastic protective carry case, this precision tool remains shielded against accidental drops, workshop dust, crushing impacts, and moisture during transport and storage.

Key Features & Specifications

• Product Type: Carbon Fiber Composite Electronic Digital Vernier Caliper.

• Measuring Range: 0 – 150 mm / 0 – 6 Inches.

• Resolution & Accuracy:

  • Resolution: 0.1 mm / 0.01 Inch.

  • Accuracy Tolerance: ±0.2 mm / ±0.01 Inch.

• Packaging & Protection: Includes a fitted, shock-resistant hard plastic storage case with internal molded cradles to keep the caliper secure and clean in toolboxes.

• Scratch-Free & Non-Conductive Carbon Fiber Construction:

  • Molded from lightweight, extra-strong carbon fiber composite material.

  • Unlike heavy steel calipers, it will not scratch or mar delicate polished metals, jewelry, gemstones, wood finishes, or automotive paint.

  • Electrically Non-Conductive: Safe for measuring live circuit boards, battery cells, electronic connectors, and magnetic components without risking short circuits.

• 4-Way Precision Measurement Modes:

  • External Measuring: Large lower jaws measure outer diameters, sheet thicknesses, and part lengths.

  • Internal Measuring: Narrow upper jaws measure inside bore diameters, pipe openings, and slot widths.

  • Depth Measuring: Integrated rear depth probe extends to measure recessed hole depths and blind cavities.

  • Step Measuring: Calibrated rear step profile measures stepped height differences between offset surfaces.

• Clear High-Contrast LCD Screen:

  • Bold, easy-to-read digital readout eliminates the eye fatigue and guesswork of squinting at tiny analog vernier scale lines.

  • One-Touch Metric / Inch Conversion: Instantly toggle between Millimeters (mm) and Inches (in) with a dedicated button.

  • Zero Setting Function: Press the "ZERO" button at any position along the scale to perform fast differential / comparative step measurements.

• Smart Power & Battery Efficiency:

  • Powered by a single standard, readily available 1.5V LR44 / SR44 button cell battery.

  • Auto-On / Auto-Off: Automatically powers on when you slide the rail and powers down after 5 minutes of inactivity to preserve battery life.

Broad Applications & Universal Use Cases

• 3D Printing & CAD Prototyping: Accurately check filament diameters, wall clearances, hole tolerances, and nozzle calibrations.

• Jewelry Making & Gemology: Measure precious stones, beads, wire gauges, and delicate rings without metal-on-metal scratching.

• Electronics & PCB Rework: Safely gauge capacitor leads, battery terminals, connector housings, and enclosure cutouts without electrical hazard.

• Woodworking & Luthier Crafts: Measure tenon widths, dowels, veneer thickness, and guitar fret depths with fingertip ease.

• Automotive & Mechanics: Check brake pad wear, spark plug gaps, hose internal diameters, and small hardware fasteners.

Quick 4-Step Setup & Operation Guide

1. Power & Battery Check: Slide open the front battery cover, install one 1.5V LR44 button cell (+ side facing up), and verify the LCD powers on.

2. Clean & Zero Calibration: Close the lower jaws completely so they touch, wipe away any dust, and press the ZERO button to set the base reading to 0.0 mm / 0.00 in.

3. Select Measurement Unit: Tap the mm / inch button to choose your preferred reading format.

4. Measure & Store: Slide the caliper jaws around or inside your workpiece to view the digital dimension; once finished, slide the caliper closed and latch it securely inside the hard plastic storage case.
