Mitutoyo 187-501 Digimatic Protractor, 150mm Blade

The Mitutoyo Series 187 Digimatic universal bevel protractor measures angles on a digital display. The blade slides and clamps along its full length, and a fine adjustment lets you set an exact angle. Toolrooms, quality control teams, machinists and fitters use it to check angles on parts, tools and set-ups.

It reads to 1' (0.01°) over -360° to 360°, and a maximum permissible error of 2' (0.03°). Resolution is the smallest step the display shows. It is not the same as accuracy, which is the biggest error Mitutoyo allows. The two models differ by blade length: 150mm for smaller work and 300mm for longer parts.
