Rumold 2,30 cm engineer's scale with DIN 1:5/5/10/20/50/100 ratios, dual cm/mm graduations, faceted edge, white detail colour for precise technical drawing.
Rumold Reduktionsmassstab – Precision Engineering Scale for Professional Drafting
The Rumold Reduktionsmassstab is a 30 cm three-sided engineer's scale designed for accurate scale measurements in technical drawing and drafting applications. It features a faceted edge profile for precise line work and clear scale graduations.
DIN-engineered scale ratios 1:2.5, 1:5, 1:10, 1:20, 1:50, and 1:100 for versatile scaling across drawing types
30 cm length with dual metric graduations in centimetres and millimetres for fine and coarse measurements
Faceted edge design ensures clean, accurate lines when tracing or marking technical drawings
White detail colour provides high contrast against dark drawing surfaces for improved readability
Das zeichnet den Rumold Reduktionsmassstab aus
Unlike standard rulers, this engineer's scale is purpose-built for technical and architectural drawing, where proportional accuracy is critical. The faceted edge and precision-milled graduations reduce measurement error, while the dual cm/mm markings allow seamless switching between coarse and fine scales without a separate tool.
Ideal für...
Technical drafters, architects, and engineering students who require reliable scale measurements in plan and elevation drawings. The DIN-standard ratios make it suitable for both classroom instruction and professional on-site drafting work where precision is non-negotiable.
Anwendung von Rumold Reduktionsmassstab
Select the appropriate scale ratio for your drawing (e.g., 1:10 for detailed sections, 1:50 for overview plans)
Align the faceted edge of the scale with the drawing baseline
Read measurements directly in centimetres or millimetres along the corresponding scale graduation
Transfer the scaled measurement to the drawing surface with a pencil or technical pen
Rumold is a Swiss manufacturer specialising in precision measuring instruments and drafting tools for technical, architectural, and engineering applications. The brand is known for durable, DIN-standard scales and rulers used in professional and educational settings. Products are distributed through Swiss office supply channels and are recognised for their accuracy and build quality.
The scale supports DIN-engineered ratios of 1:2.5, 1:5, 1:10, 1:20, 1:50, and 1:100, covering a wide range of technical drawing and drafting scales.
The scale features dual metric graduations in both centimetres (cm) and millimetres (mm), allowing measurements at two levels of precision on the same tool.
The scale is 30 cm in length, making it suitable for standard A3 and smaller drawing formats commonly used in technical and architectural work.
The scale has a faceted (three-sided) edge profile, which is the standard design for engineer's scales and ensures clean, accurate line work when tracing or marking.
The scale is a rigid plastic or durable polymer construction, typical for engineer's scales in this class, designed to resist warping and maintain graduation accuracy over time.
