Key Takeaway

What to Look for in a Digital Caliper

Before diving into the top picks, let's first understand what makes a digital caliper truly reliable.

1. Measurement Accuracy & Resolution

• Accuracy: Look for ±0.02mm (0.001 inch) or better.

• Resolution: Should be at least 0.01mm or 0.0005 inch.

2. Measurement Range

Most standard calipers offer a range of 0–150mm (6 inches), which is sufficient for most tasks. Extended ranges like 200mm or 300mm are ideal for larger industrial components.

3. Units of Measurement

Good digital calipers should support both metric and inch conversion. Some even provide fractional inch measurements.

4. Material & Build Quality

• Hardened stainless steel is preferred for durability and precision.

• Avoid plastic models for professional use.

5. Display & Controls

• A large LCD screen eases reading.

• Features like auto-zero, auto-off, and smooth sliding add to convenience.

6. Battery Life & Auto-Off

Look for models with automatic shutdown features to save battery, especially in workshop environments.

7. Additional Features

• Data output for PC connectivity (for QA departments)

• Thumbwheel for fine adjustment

• Locking screw for stability
