The PUR 180° Protractor is a high-precision mathematical instrument designed for students, educators, and technical professionals. Featuring a crystal-clear semi-circular body with crisp graduation scales, this essential layout tool makes measuring, plotting, and mapping geometric angles quick and foolproof.
Product Description
- Manufactured from premium, optical-grade clear plastic that provides total visibility of the lines underneath.
- Features a standard semi-circular 180-degree layout with dual directional scales for flexible tracking.
- Designed with a perfectly flat, straight base edge that doubles as a compact ruler for quick margin alignments.
Key Features
- Measurement Accuracy: Formulated with clear degree markings running from 0° to 180° in both clockwise and counter-clockwise directions.
- Material Integrity: Constructed from a flexible, shatter-resistant polymer built to withstand everyday transport in school backpacks.
- Center Point Anchor: Features a dedicated, high-visibility center crosshair target to align perfectly over geometric vertices.
- Compact Profiling: Slim and lightweight design that drops easily into any standard metal or fabric pencil box.
Best Uses
- School & College Geometry: The perfect daily companion for secondary, matriculation, and high school students solving trigonometry theorems, drawing polygons, and mapping vectors.
- Engineering & Architecture Drawing: Ideal for technical design learners drafting introductory blueprints, perspective grids, and precise layout angles.
- Art & Pattern Layouts: Excellent tool for mandala artists, graphic crafters, and pattern makers requiring uniform angular spacing.
Product Tips
- Scale Protection: Avoid scraping the protractor against sharp metal compass tips to prevent scratching off the printed degree increments.
- Cleaning Routine: Wipe away graphite pencil dust using a soft dry cloth; do not use chemical solvents or alcohol wipes as they can fade the measurement scales.
