Description

Arriving late October 2025 for delivery – Pre-order now

Condition: This Marui Keiki MP-101 dial (micro) protractor is used, but presents like new. It shows minimal signs of handling and appears to have been very lightly used. All angles, clamps, and adjustment mechanisms operate smoothly and precisely.

The MP-101 is a full-circle (0–360°) micro protractor engineered for demanding angle measurement tasks. It features a direct-reading micro head with a 1′ (one minute) increment resolution, allowing fine angular measurement without interpolation. A one-touch coarse/fine/rotation clamp permits quick coarse movement and precise fine adjustments in a single control. The hardened stainless steel body ensures durability, while its design permits measurement of both internal and external angles, sheet-metal bends, and prism optics.

Marui Keiki is a Japanese precision metrology manufacturer, respected for its high-quality angular measurement instruments. The MP series micro protractors are favored in toolrooms, inspection labs, and metrology departments because of their rigidity, minimal backlash, and fine angular control. Their robust construction supports long-term repeatability in industrial use.
