360-degree full-circle design enables measurement from any direction without flipping the tool
12 cm length with centimetre markings provides versatile short-range measurement capability
Light green elastika construction offers flexibility and resistance to breaking under pressure
Faceted edge type ensures clear, precise alignment against drawn lines and surfaces
Das zeichnet das Arda Kreislineal aus
Unlike standard half-circle protractors, the 360° full-circle design eliminates the need to rotate or flip the ruler when measuring angles from different orientations. The elastika material provides a slight flex that aids contact with curved surfaces while maintaining dimensional accuracy.
Ideal für...
Students in geometry and technical drawing classes, architects and designers working with scale models, and office professionals who require quick angular measurements for layout and planning tasks. The compact 12 cm size fits comfortably in pencil cases and desk drawers.
Anwendung von Arda Kreislineal
Place the ruler flat on the surface to be measured. Align the centre point with the angle vertex. Read the degree marking where the other arm of the angle crosses the scale. For linear measurement, use the centimetre scale along the straight edge. The faceted edge helps keep the ruler stable during measurement.
