The MINERVA Usine 180° Protractors are professional-grade mathematical measuring instruments widely used in schools, for architectural drawing, and in technical fields.They are known for their optical clarity and durability.
These protractors are made from 2 mm thick, robust, crystal-clear Altuglas (optical-quality thermoplastic) featuring a faceted edge to maximize readability. They are formatted with a 180° scale displaying both clockwise and counterclockwise (trigonometric) orientations.
MINERVA Usine 180° Protractors are laser-cut and hand-finished with photoengraved scales ensuring ultra-fine half-degree division markings. The printing resists smearing, dirt, and fading, and can safely be cleaned using water or alcohol without degrading the scale. They are also equipped with an integrated central pointer and a convenient central grip zone for steady drafting.
