The 190mm Semi-Circular Protractor is designed for precise angle measurement where a flat baseline is required. Its half-circle format provides clear, easy-to-read measurements from 0 to 180°, making it ideal for technical drawing, geometry, and layout work.
Manufactured from durable transparent acrylic, it offers excellent visibility for accurate alignment, while the printed graduations ensure consistent, reliable readings. The straight edge along the base also allows for quick line work and stable positioning during use.
Larger in size for improved readability and control, this protractor is well-suited to classroom, studio, and professional environments where clarity and precision are essential.
A smaller 110mm version of this 190mm Semi-Circular Protractor is available here.
