The Mitutoyo Depth Base Attachment is an optional accessory that expands a caliper’s measurement capabilities to include precise depth checks. Designed for digital, vernier, and dial calipers that feature a depth measuring bar, the 75 mm wide base provides a stable platform for repeatable depth readings across 100, 150, and 200 mm ranges.

This attachment helps technicians, engineers, and hobbyists achieve accurate measurements with less effort by offering a flat, finely ground base surface and a secure locking clamp that stays in place during use.

• Multi‑caliper compatibility: Works with digital, vernier, and dial calipers that have a depth measuring bar, enabling depth checks without swapping instruments.
• Finely ground base surface: Provides a flat, stable contact point for consistent, repeatable depth readings.
• Secure locking clamp: Holds the attachment firmly in position for reliable measurements and reduced drift during use.

When you add this depth base to your workflow, you gain a reliable reference for depth measurements, improving accuracy and speeding up setups. The 75 mm width, combined with a stable base and locking mechanism, supports efficient, repeatable results in everyday machining, inspection, and assembly tasks across 100, 150, and 200 mm ranges.
