All original documentation and the inspection certificate are included.+1
Product Overview
The Mitutoyo 187-901 is a high-precision angle measuring instrument designed for the accurate layout and inspection of machinery, moulds, and jigs. Unlike standard protractors, this “Universal” model features a measuring range of 360° (divided into four 90° quadrants), allowing for the measurement of any angle on a workpiece.+1
The instrument uses a high-contrast Vernier Scale that offers a resolution of 5 minutes (5′) (or 1/12th of a degree), enabling far greater precision than simple degree-graduated tools. It is equipped with a magnifying glass built over the vernier scale to make reading these fine graduations easy and error-free. The protractor comes with two interchangeable blades (150mm and 300mm), which can be slid and clamped at any point along their length to suit the size of your part. Additionally, it can be attached to a standard Height Gauge using the included holder, allowing for precise angle transfer on a surface plate.+1
